If you're reading this at 2am, three days before your ACL reconstruction, heart racing with anxiety about what's ahead – I get it. I've been exactly where you are. Both as a patient with my own ACL tear in 2017, and as a sports therapist who's treated hundreds of ACL patients in English Premier League clubs and my private injury rehabilitation clinics across the UK.
Your surgeon probably told you: "It's straightforward, you'll be fine, see you in 6 weeks." Your physiotherapist might have mentioned "some discomfort" and "gradual progress." But nobody really prepared you for what the first two weeks ACTUALLY feel like.
This isn't the sanitized hospital leaflet version. This is the reality – the good, the difficult, and the genuinely challenging moments that every ACL patient faces. I'm writing this because I wish someone had given me this honest conversation before my surgery. Not to scare you, but to prepare you. Because when you know what's coming, you can face it with confidence instead of fear.
FIRST 2 WEEKS AT A GLANCE
Timeline:
- Days 1-3: Nerve block wearing off, heavy pain meds, minimal movement
- Days 4-7: Pain peaks, sleep disrupted, frustration sets in
- Days 8-10: Turning point – pain decreases, hope returns
- Days 11-14: Mobility improving, feeling more human
Hardest Parts (from 200+ patients):
- First bowel movement (pain meds cause severe constipation)
- First night without nerve block
- Showering while keeping wound dry
- Dependency on others for basic tasks
- Boredom and mental fatigue
Essential Supplies:
- ✓ Stool softener (start Day 1 – this is crucial!)
- ✓ Extra pillows for elevation (at least 3-4)
- ✓ Compression ice machine or ice packs
- ✓ Grabber tool for dropped items
- ✓ Entertainment (Netflix series, audiobooks, podcasts)
- ✓ Shower chair or stool
- ✓ Loose-fitting clothing
Days 1-3: The Honeymoon Phase
Day 1: Surgery Day
You'll wake up in recovery feeling groggy but surprisingly pain-free. This is the nerve block doing its job – a local anesthetic that numbs your entire leg for 12-24 hours post-surgery. Don't be fooled by this false sense of security. I've had countless patients tell me they thought "this isn't so bad" on Day 1, only to be shocked when reality hit 24 hours later.
Your leg will feel like it doesn't belong to you. One of my patients described it as "dragging around a dead log that used to be my leg." This is completely normal. The numb patch on the side of your knee? Also normal. It may never feel exactly the same again, but it won't affect function.
Getting Home: Someone will need to drive you home and help you get comfortable. You'll likely have:
- A large, cumbersome brace locked straight
- Bulky dressings wrapped around your knee
- Crutches that feel awkward and unwieldy
- Prescription pain medication and instructions
First Night Expectations: Sleep will be difficult. Your leg needs to stay elevated – use at least 3 pillows under your calf and ankle (not directly under the knee). Set alarms for your pain medication schedule. Don't try to be a hero and skip doses because you "feel fine" – the nerve block is masking everything.
Days 2-3: The Calm Before the Storm
This is when the nerve block wears off completely. For most patients, this happens gradually between 12-36 hours post-surgery. You'll notice sensation returning – first as tingling, then as a deep, throbbing ache.
Why You Might Feel "This Isn't So Bad": The inflammation is still building. Your body is in initial shock. The heavy-duty pain medication is still very effective. This creates a window where you might think everyone exaggerated the difficulty. They didn't. They just knew what Day 4 brings.
Critical Medication Timing: Stay ahead of the pain. Set alarms for every dose. Missing even one can send you into a pain spiral that takes hours to recover from. I learned this the hard way on Day 3 when I thought I could stretch the gap between tablets from 4 hours to 6. I regretted it immediately.
The Bathroom Situation (Let's Be Honest): This deserves its own section because nobody warns you adequately. One of my patients, a father of five, told me: "I watched my wife give birth five times. Trying to have my first bowel movement after ACL surgery was the closest I've come to understanding that experience."
Pain medications, particularly opioids, cause severe constipation. The combination of:
- Reduced mobility
- Dehydration
- Narcotic pain medication
- Trying to use the toilet with one leg essentially immobilized
...creates a perfect storm. Start taking stool softeners on Day 1. Not Day 3 when you're desperate. Day 1. Drink ridiculous amounts of water. Eat fiber where possible. This is not optional advice.
For urination, having a raised toilet seat or a commode chair can be a game-changer, especially in those first few days when lowering down to a standard toilet feels impossible.
Starting Gentle Exercises: Your physiotherapist will have given you simple exercises to begin immediately:
Quad Sets (Isometric Quadriceps Contractions): Lie flat with your leg straight. Tighten your thigh muscle by actively squeezing it, which will slightly straighten your leg and press your knee into the floor. Lift your heel slightly. Hold for 2-3 seconds. This feels impossible at first – your brain sends the signal but nothing happens. This is called "quad inhibition" and it's frustratingly normal. Keep trying. 3 sets of 10, three times per day.
Ankle Pumps: Point your toes, then flex them back. This helps prevent blood clots and reduces swelling. Do these constantly while sitting or lying down.

Days 4-7: The Reality Check
Let me be completely honest with you: this is typically the hardest week of your entire ACL recovery. Not Week 12 when you're frustrated about not running yet. Not Month 6 when you're impatient to return to sport. Week 1. Specifically, Days 4-7.
Why This Week is the Hardest
The Pain Curve: Inflammation peaks around Days 5-7. While your surgical site is healing, your body is mounting a massive inflammatory response. Your knee will be swollen, hot, and throbbing. The pain often feels worse than it did on Day 1 because the nerve block honeymoon is completely over.
Cumulative Sleep Debt: By Day 4, you've had 3-4 nights of terrible sleep. You can't get comfortable. The brace is restrictive and hot. Every time you shift position, your knee reminds you why that's a bad idea. You're waking up every 1-2 hours. The exhaustion compounds daily.
One patient told me: "I hadn't slept for 3 days and was absolutely delirious by Day 5. I cried because I dropped my phone and couldn't reach it. Not because of my knee – because of the phone."
Psychological Impact of Helplessness: You can't shower alone. You can't put on your own socks. You can't carry a cup of coffee from the kitchen to the couch. The dependency on others – for everything – takes a serious toll on your mental health. This is especially hard if you're typically very independent.
Managing the Pain
Medication Schedule: Continue following your prescribed pain medication schedule religiously. Don't try to wean off too quickly because you're worried about dependence. Week 1 is not the time to be a hero. That said, be aware that prescription opioids can be addictive. Use them as prescribed, no more. Plan with your doctor for when and how you'll reduce them (typically around Week 2).
RICE Protocol:
- Rest: This is non-negotiable. Your body is healing.
- Ice: Use your compression ice machine for 20 minutes every 2-3 hours. This reduces inflammation and numbs pain.
- Compression: Your brace and wraps provide this.
- Elevation: Keep your leg elevated above heart level as much as possible.
When to Call Your Surgeon (Red Flags): Seek immediate medical attention if you experience:
- Fever over 38.5°C (101.3°F)
- Redness spreading from the wound
- Red streaks going up your leg
- Hot, tender calf (possible blood clot)
- Excessive bleeding or discharge from incision
- Inability to urinate
- Severe pain uncontrolled by medication
- Numbness or weakness in your foot that worsens
The Sleep Problem
Sleep disruption is one of the most underestimated challenges of early ACL recovery. Here's why you can't get comfortable:
The Brace Frustration: It's locked straight, it's heavy, it's hot, and it prevents you from finding your normal sleep position. If you're a side or stomach sleeper, being forced onto your back is genuinely distressing.
Pillow Positioning Strategies:
- Under your calf and ankle: Keeps knee elevated, reduces swelling
- Between your knees (if allowed to side-sleep): Prevents leg rolling
- Under your lower back: Reduces back pain from unusual positioning
- Body pillow: Provides support and something to hold
Realistic Expectations: You won't sleep in 7-8 hour blocks. Accept that you'll sleep in 1-2 hour chunks. This is temporary. By Week 3, sleep will improve dramatically.
Pain at Night: Pain often feels worse at night. Why? Because:
- You're lying still (less distraction)
- Inflammation builds while stationary
- Medication may be wearing off
- You're exhausted, which lowers pain tolerance
Set an alarm for your midnight pain medication dose. Don't wait until you wake up in agony.
The Back and Hip Pain Nobody Warns You About
Within days of ACL surgery, many patients develop significant pain in their:
- Lower back: From unusual sleeping positions and lack of movement
- Hip (surgery side): From altered gait and muscle compensation
- Other knee: From bearing all the weight and doing all the work
Multiple patients in the Reddit research reported: "The back and hip pain were actually worse than the knee for me!"
What Helps:
- Gentle stretching of your non-injured leg
- Using heat on your back (not your knee)
- Changing positions frequently when awake
- Light massage from a partner
- Anti-inflammatory medication
Mental Survival
Day 6 post-op from my own surgery, I texted a physiotherapist colleague: "I've made a terrible mistake. My knee will never work again. I can't even lift my leg." She replied: "Everyone says that on Day 6. Call me on Day 10." She was right. Day 10 felt like a different universe.
This is Temporary: Write this down and put it where you can see it: "Every day after Day 5 gets better." Because it does. Day 6 is better than Day 5. Day 7 is better than Day 6. The increments feel tiny, but they're real.
Set Micro-Goals: Forget about "running in 6 months." Focus on:
- Making it to the bathroom without help
- Doing your quad sets without your partner assisting
- Sleeping for 3 hours straight
- Bending your knee 5 degrees more than yesterday
Ask for Help Without Guilt: This is hard for independent people. But you need help. Accept it. Thank people genuinely. And know that you'll return the favor when you can.
Combat the Boredom: Line up entertainment in advance:
- Netflix series you've been meaning to watch
- Audiobooks (easier than reading when medicated)
- Podcasts
- Gentle video games
- Online courses in something you're interested in
The mental battle is as real as the physical one. Acknowledge it. Don't minimise it.
Days 8-10: The Turning Point
This is where hope returns. I promise.
What Changes
Pain Decreases Noticeably: From 7-8/10 to 4-5/10. Still uncomfortable, but manageable. You can think more clearly because you're taking less heavy medication. Your personality starts to return.
The Quad Starts "Firing": This is a small but massive victory. For a week, you've been sending signals to your quadriceps muscle and getting nothing in response. Suddenly, you contract and your leg actually moves. You might cry. I did. It's normal.
Sleep Improves: You might sleep for 3-4 hours straight. This feels miraculous after a week of 90-minute chunks.
Swelling Starts Reducing: Not dramatically, but you can see your kneecap again. Your calf doesn't look like a balloon. Progress.
Physical Milestones
Crutches Feel More Stable: You've developed a rhythm. You're not terrified of falling every time you stand up. Movement, while still slow, feels less precarious.
Weight-Bearing Progress: If you're allowed to bear weight (ACL-only repairs usually are), you can probably put more pressure through your leg. You might even take a few steps with a very pronounced limp but without crutches. Don't push this – follow your protocol.
Range of Motion Exercises Less Painful: Heel slides to 90 degrees (if permitted) still aren't pleasant, but they don't make you want to scream anymore. You might even see 5-10 degrees of improvement from Day 7 to Day 10.
Psychological Shift
Hope Returns: You can envision recovery now. For a week, it felt impossible. Now you can see a path forward, even if it's long.
Less Dependent on Others: You can probably reach the bathroom alone (even if slowly). You might shower with minimal assistance. These tiny victories matter enormously to your mental state.
Boredom Replaces Fear: This is actually a good sign. When you're bored, it means you're not in survival mode anymore. You're ready to think about the future.
Days 11-14: Momentum Building
Physical Progress
Walking Pattern Improving: Your gait is still abnormal – you're probably still in a brace and using at least one crutch – but there's visible improvement. You might be cleared to unlock your brace for certain activities or to remove it while sitting.
Less Pain Medication: Many patients transition off prescription medications entirely during Week 2, moving to over-the-counter options like paracetamol and ibuprofen. Some still need occasional stronger medication, especially at night. Both are normal.
Exercises Feeling Easier: Your exercise sheet might still only have 4-5 exercises on it, but you can do them with better control and less compensation. Your quad is waking up. Your range of motion is improving daily.
Swelling More Manageable: By Week 2, you understand the pattern: leg down for too long equals swelling increase. Elevation and ice equals reduction. You can manage it proactively rather than reactively.
Independence Returning
Showering Alone: With the right setup (shower chair, waterproof cast cover, hand-held shower head), most patients can manage showering independently by Week 2. This feels like reclaiming a piece of your dignity.
Moving Around Home: Short distances without crutches might be possible. Kitchen to couch. Bedroom to bathroom. You're still very cautious, but you're mobile.
Driving Clearance Conversation: If it's your left knee and you drive an automatic, you might discuss driving clearance with your surgeon. If it's your right knee, you're looking at 4-6 weeks typically. Don't rush this – your reaction time isn't normal yet.
Thinking About Work Return: For desk jobs, Week 3-4 is often realistic if you can elevate your leg and take breaks. For physical jobs, it's much longer. Have this conversation with your surgeon.
Setting Up for Success
First Physiotherapy Appointment: You'll likely see your physiotherapist around Week 2. They'll assess:
- Range of motion (flexion and extension)
- Swelling levels
- Gait pattern
- Quad activation
- Pain levels
They'll progress your exercises slightly and give you goals for Weeks 3-6.
Goals for Weeks 3-6:
- Full extension (straight leg)
- 90-125 degrees of flexion
- Walking without crutches
- Minimal swelling
- Good quad control
- Beginning single-leg exercises
When to Push vs When to Rest: This is a crucial balance that will define your entire recovery. In Week 2:
Push when:
- Doing prescribed exercises
- Working on range of motion
- Building quad activation
- Challenging yourself within pain limits
Rest when:
- Swelling increases
- Pain exceeds 5/10
- You're exhausted
- Your body signals overload
Signs You're On Track:
- Daily improvements, however small
- Decreasing pain over the 2-week period
- Improving sleep quality
- Good surgical site healing
- Following your exercise protocol
- Swelling reducing with elevation

Red Flags: When to Seek Immediate Help
Call Your Surgeon Immediately If:
Infection Signs:
- Temperature above 38.5°C (101.3°F)
- Redness spreading from the surgical site
- Red streaks going up your leg from the knee
- Wound feels hot to touch
- Yellow or green discharge from incision
- Foul smell from wound
- Generally feeling unwell or flu-like symptoms
Blood Clot Warning Signs (DVT):
- Hot, swollen, tender calf
- Redness and warmth in lower leg
- Sudden swelling in one leg only
- Shortness of breath (potential pulmonary embolism – call 999/emergency services)
- Chest pain
Nerve or Circulation Issues:
- Foot or toes turning blue, white, or very pale
- Loss of sensation in foot that's worsening
- Inability to move your foot or toes
- Severe numbness that's spreading
Graft or Surgical Complications:
- Knee locked in a fixed position and won't move
- Severe instability (knee giving way completely)
- Excessive bleeding that soaks through dressings
- Sudden, severe pain that's different from post-op pain
Medication Issues:
- Inability to urinate (can indicate urinary retention)
- Severe nausea and vomiting preventing fluid intake
- Allergic reaction to medication (rash, difficulty breathing, swelling)
General Medical Advice:
When in Doubt, Call: It's better to have a 5-minute conversation with your surgical team and be reassured than to ignore something serious. They'd rather you called unnecessarily than missed something important.
Out of Hours: Know your hospital's emergency contact number. It should be in your discharge paperwork; failing that, don't be nervous about calling 999 or 112!
What I Wish I'd Known: Advice from 100+ ACL Patients
Expectations vs Reality
"Nobody told me my whole leg would be numb in patches"
That numb feeling on the side of your knee? It might be permanent. It doesn't affect function, but it feels weird. This is from nerve damage during surgery and is completely normal.
"I didn't expect to feel so weak so quickly"
One week of immobility equals significant muscle atrophy. Your quad will look noticeably smaller. This is expected and reversible with rehabilitation.
"The mental challenge surprised me more than the physical"
The psychological impact of dependency, loss of mobility, and facing a long recovery is real. Be prepared for emotional days. This doesn't make you weak – it makes you human.
The Comparison Trap
Looking back at my own recovery, I wish someone had told me that the frustration was normal. That wanting to cry because I couldn't put my own socks on at age 32 didn't make me weak – it made me human.
I wish I'd known that the person on Instagram running at 8 weeks probably:
- Had a different injury/surgery than me (maybe ACL-only vs ACL + meniscus)
- Was showing their best moment, not their everyday reality
- Might be headed for a re-tear by pushing too hard
Every ACL recovery is different.
Variables that affect your timeline:
- Type of graft (patellar, hamstring, quad, allograft)
- Meniscus involvement
- Other ligament damage
- Your age and baseline fitness
- Quality of your surgeon and physiotherapist
- Compliance with rehabilitation
- Your body's individual healing response
The person who's back to running at 12 weeks isn't "better" than you. They're on a different path.
Small Things That Make a Big Difference
A shower chair: Makes you feel human again. Worth every penny.
Long phone charger cable: So you don't have to move to charge your phone.
Slip-on shoes: You won't tie laces for weeks.
Button-up shorts/trousers: Much easier than pull-on clothes.
Netflix watch list ready: Have 20+ hours of entertainment lined up.
A bell or phone always nearby: For calling for help when you need it.
Healthy snacks within reach: You can't easily get up and down.
Insulated water bottle with straw: Staying hydrated is crucial but difficult.
Things That Don't Help (But People Will Suggest)
"You'll be back to normal before you know it!"
No. This is a 9-12 month process. False optimism doesn't help.
"My friend was running at 6 weeks!"
Your friend probably wasn't. Or shouldn't have been.
"Just stay positive!"
Toxic positivity doesn't acknowledge real struggle. It's okay to have hard days.
"Everything happens for a reason!"
Sometimes ligaments just tear. There doesn't need to be a cosmic lesson.
What Actually Helps
Validation: "This is really hard. You're doing great."
Specific offers: "I'm going to the shop – what can I get you?" (not "let me know if you need anything")
Realistic timelines: "Month 3 will feel so different to now. One day at a time."
Company without pressure: Just sitting with you while you elevate your leg.
Belief in the process: "You're going to recover. It takes time. That's normal."
Conclusion: You Will Get Through This
If you're reading this pre-surgery, terrified: you're going to be okay. The first two weeks are genuinely difficult. I won't lie to you about that. There will be moments of pain, frustration, and doubt.
But here's what's also true:
Every single ACL patient I've treated has said the same thing at 6 months: "I wish I hadn't worried so much in those first weeks. It felt like forever, but it was just a tiny part of my recovery."
This is temporary suffering for long-term gain. You're not just fixing a ligament – you're building a stronger, more stable knee than you had before your injury. Every day past Day 5 gets better. Some days the improvement is tiny. But it's there.
Week 2 feels like forever. Month 3 feels like yesterday.
You're stronger than you think. Your body knows how to heal – you just have to give it time and follow the process. Trust your medical team. Do your exercises. Rest when you need to. Push when it's appropriate.
And remember: thousands of people have walked this exact path before you. They survived Week 1. They got through Day 6. They cried over dropped phones and celebrated quad contractions. They doubted themselves and then they healed.
You will too.

Frequently Asked Questions
How long does pain last after ACL surgery?
Severe pain typically peaks around Days 4-7 and significantly reduces by Day 10-14. Most patients transition off prescription pain medication within 2 weeks, though aching and discomfort can persist for 4-6 weeks. Pain during exercises may continue for several months but should be manageable and gradually decreasing.
Can I sleep on my side after ACL surgery?
For the first 1-2 weeks, sleeping on your back with your leg elevated is strongly recommended. After Week 2, you can try modified side positions with pillow support between your knees, though comfort varies by individual. Full side/stomach sleeping usually returns around Week 6-8 as brace requirements decrease and knee comfort improves.
When can I shower after ACL surgery?
You can typically shower 48-72 hours after surgery, keeping the incision dry with a waterproof covering or plastic wrap sealed with tape. Many surgeons provide specific dressing covers. Full submersion (bath, swimming pool) is usually cleared at 2-3 weeks once incisions are fully healed and dressings permanently removed.
What can I eat after ACL surgery?
Focus on high-protein foods (lean meats, eggs, fish, Greek yogurt) to support tissue healing, anti-inflammatory foods (berries, leafy greens, salmon, turmeric), and plenty of fiber to combat constipation from pain medication. Stay very well hydrated – aim for 2-3 liters of water daily. Collagen-rich foods like bone broth may support ligament healing.
How long do I need to use crutches after ACL surgery?
Crutch duration depends on your specific surgery protocol. For ACL-only repairs with immediate weight-bearing allowed, expect 1-3 weeks. If you had meniscus repair requiring non-weight bearing protection, you may need crutches for 4-6 weeks. Always follow your surgeon's specific protocol – pushing to ditch crutches too early risks graft damage.
When can I drive after ACL surgery?
For left knee surgery with automatic transmission, driving may be possible around 2-4 weeks if you can perform an emergency stop comfortably. For right knee or manual transmission, expect 6-8 weeks minimum. You must be off narcotic pain medication, have adequate knee control, and be cleared by your surgeon. Check your car insurance policy requirements.
Is it normal for my knee to feel numb after ACL surgery?
Yes, patches of numbness around the surgical site are completely normal and often permanent. This is due to small nerve damage during the procedure. The numb area is typically on the outer side of the knee and doesn't affect function. Sensation may partially return over 6-12 months but some permanent numbness is expected.
How much swelling is normal after ACL surgery?
Significant swelling is expected for the first 2-3 weeks, with swelling peaking around Days 5-7. Your knee will look larger than normal, feel tight, and may extend down to your ankle. Swelling should gradually decrease with elevation, ice, and compression. If swelling suddenly worsens, becomes very hot, or is accompanied by fever, contact your surgeon.
