Most twisted ankles are mild sprains that heal well at home with the right approach. The key is protecting the joint for the first few days, then gradually reintroducing movement and strengthening exercises to prevent the injury from becoming a recurring problem. A mild sprain typically heals in one to two weeks, while a severe tear can take several months.
What Happens When You Twist Your Ankle
A twisted ankle stretches or tears the ligaments that hold the joint together. Most twists roll the foot inward, damaging the ligaments on the outside of the ankle. The severity breaks down into three grades:
- Grade 1 (mild): The ligament is stretched but not torn. You’ll have some swelling and tenderness but can usually still walk.
- Grade 2 (moderate): A partial tear of the ligament. Swelling is more noticeable, the area is painful to touch, and putting weight on it is difficult.
- Grade 3 (severe): A complete ligament tear. The ankle feels unstable, swelling is significant, and walking is extremely painful or impossible.
First Steps Right After the Injury
In the first one to three days, your priority is to protect the ankle and control swelling. Reduce or restrict movement during this window to minimize bleeding inside the tissue and prevent further damage to the injured ligament fibers. Pain is your guide here: if something hurts, stop doing it. But don’t stay completely off the ankle longer than necessary, because prolonged rest weakens the tissue.
Wrap the ankle with a compression bandage or use athletic tape. Compression limits swelling and internal bleeding in the joint, and studies show it improves comfort and quality of life after an ankle sprain. Whenever you’re sitting or lying down, prop your foot up above the level of your heart. This helps fluid drain away from the injured area and reduces puffiness.
Rethinking Ice and Pain Relievers
You’ve probably heard of the old RICE protocol (rest, ice, compression, elevation). The updated approach, published in the British Journal of Sports Medicine, actually questions two pillars of that advice: ice and anti-inflammatory medications like ibuprofen.
The reasoning is straightforward. Inflammation isn’t a malfunction. It’s your body’s repair process. The swelling, warmth, and tenderness you feel after a sprain reflect immune cells flooding the area to clean up damaged tissue and begin rebuilding. Anti-inflammatory drugs can blunt that response, and at higher doses, they may interfere with long-term tissue healing. Ice works as a pain reliever, but it may also slow the arrival of those repair cells, delay the formation of new blood vessels, and lead to weaker scar tissue.
This doesn’t mean you need to suffer. If pain is keeping you from sleeping or functioning, a short course of over-the-counter pain relief at a low dose is reasonable. Just know that reaching for ibuprofen reflexively in the first 48 hours may not be doing your ligament any favors. For pain control without disrupting inflammation, acetaminophen is an alternative worth considering.
When to Start Moving Again
Early, gentle movement is one of the most important things you can do for a sprained ankle. As soon as the initial pain allows (often within a few days for a mild sprain), start adding light mechanical stress. This means walking short distances, doing gentle ankle circles, or writing the alphabet in the air with your toes. Controlled loading promotes repair and remodeling of the damaged ligament through a process called mechanotransduction, where physical force signals cells to lay down stronger tissue.
The goal is to resume normal activities as soon as symptoms allow, without pushing through sharp or worsening pain. A good rule of thumb: discomfort during movement is acceptable, but pain that gets worse or lingers afterward means you’ve done too much.
Exercises That Prevent Reinjury
Here’s the part most people skip, and it’s the reason ankle sprains so often happen again. A sprain damages not just the ligament but also the nerve endings that tell your brain where your foot is in space. Without targeted rehab, that sense of balance and position (called proprioception) stays impaired, and your ankle remains vulnerable.
A conditioning program from the American Academy of Orthopaedic Surgeons targets the muscles that stabilize the ankle: the calf muscles, the muscles along the shin, and the muscles running down the outside of the lower leg. Start with these once the initial pain has subsided:
- Single-leg balance: Stand on your injured foot for 30 seconds at a time, holding a chair for support if needed. Progress to doing it with your eyes closed as your balance improves.
- Calf raises: Stand on both feet and slowly rise onto your toes, then lower back down. Work toward two sets of 10. As you get stronger, try single-leg calf raises on just the injured side.
- Resistance band exercises: Loop a resistance band around the ball of your foot and push your foot outward (eversion) against the band. This specifically targets the muscles on the outer leg that resist the inward rolling motion that caused the sprain.
- Towel scrunches: Place a towel on the floor and use your toes to scrunch it toward you. This strengthens the small muscles in the foot and the tissue along the sole.
Do these exercises six to seven days a week during recovery, then three to five days a week as ongoing maintenance. The AAOS describes this as a “lifelong protection” approach for ankle health.
Bracing vs. Taping for Support
If you’re returning to sports or physical activity, external ankle support can cut your risk of reinjury. Both taping and bracing work, and athletes with a history of ankle sprains benefit even more than those without prior injuries. That said, most studies find bracing is slightly more effective. One study tracking 300 football players over six years found that wearing an ankle brace was twice as effective at preventing ankle injuries compared to taping. Braces also hold up better during prolonged activity, since tape loosens with sweat and movement.
Signs You May Need an X-Ray
Not every twisted ankle needs imaging. Doctors use a set of criteria called the Ottawa Ankle Rules to determine whether an X-ray is warranted. You likely need one if you have ankle pain plus any of the following:
- Bone tenderness when you press on the bony bumps on either side of the ankle
- Bone tenderness along the midfoot (the area between your ankle and toes)
- Inability to bear weight for four steps, both right after the injury and when you’re evaluated
If you can hobble on it (even painfully) and pressing the bones doesn’t reproduce sharp, pinpoint pain, a fracture is unlikely.
How to Spot a High Ankle Sprain
Most ankle sprains damage the ligaments on the outside of the joint. A high ankle sprain is different. It injures the ligament connecting the two bones of the lower leg (the tibia and fibula) just above the ankle. These injuries are trickier because they often don’t look serious from the outside. Swelling and bruising are minimal, which can be misleading.
The telltale signs are pain that radiates up the leg from the ankle, pain that worsens when you pivot or rotate your foot, and significant difficulty bearing weight despite relatively little visible swelling. A doctor can test for this by squeezing the two leg bones together midway up the calf. If that squeeze sends pain shooting down toward the ankle, a high ankle sprain is likely. Unlike a standard sprain, high ankle sprains often require a period of limited weight-bearing and more structured bracing, so they’re worth getting evaluated.
Realistic Recovery Timelines
A Grade 1 sprain typically heals in one to two weeks. You’ll feel sore and stiff, but walking and daily activities should be manageable fairly quickly. Grade 2 sprains generally take several weeks, with a gradual return to full activity over four to six weeks depending on how consistently you do your rehab exercises. Grade 3 sprains involving a complete ligament tear can take several months, and some require surgery followed by a longer rehabilitation period.
The biggest predictor of a smooth recovery isn’t the severity of the initial injury. It’s whether you do the balance and strengthening work afterward. People who skip rehab are significantly more likely to sprain the same ankle again, sometimes developing chronic ankle instability that affects them for years. The exercises aren’t optional, they’re the core of the fix.
