Most sprained ankles heal fully with home treatment: protect it for the first few days, then gradually reload it with movement and exercises. A mild sprain typically heals in one to two weeks, while a complete ligament tear can take several months. The key is matching your treatment approach to the severity of the injury and resisting the urge to do too little or too much at each stage.
How to Tell How Severe Your Sprain Is
Ankle sprains are graded on a three-point scale based on how much ligament damage has occurred. A Grade 1 sprain means the ligament has been stretched or slightly torn. You’ll have mild tenderness, some swelling, and stiffness, but the ankle still feels stable and you can usually walk with minimal pain.
A Grade 2 sprain involves a more significant but still incomplete tear. You’ll notice moderate pain, swelling, and bruising, and the injured area is tender to touch. Walking is painful but possible. A Grade 3 sprain is a complete tear of one or more ligaments. It causes severe swelling and bruising, the ankle feels unstable or “gives out,” and walking is likely not possible due to intense pain.
If you can’t take four steps on the ankle right after the injury, or if you have sharp tenderness when pressing on the bony points on either side of your ankle or the top of your midfoot, you should get an X-ray to rule out a fracture. These are the same criteria emergency physicians use to decide whether imaging is needed.
What to Do in the First 1 to 3 Days
The outdated advice for sprains was RICE: rest, ice, compression, elevation. A more current framework published in the British Journal of Sports Medicine uses the acronym PEACE for the acute phase, and it challenges some common assumptions about early treatment.
Protect the ankle. Limit movement and avoid putting weight on it for one to three days. This minimizes bleeding inside the joint and prevents further damage to the torn fibers. But don’t rest too long. Prolonged immobilization actually weakens the healing tissue. Let pain be your guide for when to start moving again.
Elevate often. Keep the ankle above heart level when you’re sitting or lying down. This helps drain fluid from the swollen tissue. The evidence for elevation isn’t strong, but the risk is essentially zero and it tends to feel better.
Compress the area. Wrap the ankle with an elastic bandage or use a compression sleeve. This limits swelling inside and around the joint and has been shown to improve quality of life after ankle sprains.
Be cautious with anti-inflammatory painkillers. This is the surprising one. Inflammation is not just a side effect of injury. It’s the first stage of healing. Taking ibuprofen or similar drugs, especially at higher doses and in the first few days, may actually delay tissue repair. There is a growing body of evidence that these medications interfere with the natural healing process, even though they reduce pain in the short term. If the pain is manageable, acetaminophen (which controls pain without suppressing inflammation) is a reasonable alternative.
When to Start Moving Again
The second half of the modern framework is called LOVE, and it focuses on what happens after the first few days. The central message: an active recovery beats a passive one.
Load the ankle early. As soon as symptoms allow, start putting weight on the ankle and moving it through its range of motion. This might feel counterintuitive, but mechanical stress is what signals the ligament to rebuild stronger. The goal is to find the level of activity that challenges the tissue without increasing pain. Normal activities should be resumed as soon as you can tolerate them.
Start pain-free cardio. A few days after the injury, begin some form of cardiovascular exercise that doesn’t aggravate the ankle. Swimming, cycling, or using an upper-body ergometer all count. This increases blood flow to the healing structures and helps keep your mood and motivation up, which genuinely matters for recovery. Psychological factors like fear of re-injury and catastrophic thinking are linked to worse outcomes.
Passive treatments like ultrasound therapy, acupuncture, or manual therapy in the early stages have shown minimal benefit for pain or function compared to simply staying active. In some cases, they can be counterproductive by reinforcing the idea that recovery is something done to you rather than by you.
Rehabilitation Exercises by Phase
Range of Motion
Start these as soon as you can move the ankle without sharp pain, often within the first few days for a mild sprain. Sit so your feet don’t touch the floor and use your big toe to trace each letter of the alphabet in the air. Do this twice daily. You can also loop a towel around the ball of your foot, keep your leg straight, and gently pull the towel toward you, holding for 30 seconds. Repeat 10 times. These movements restore flexibility and help clear swelling from the joint.
Calf stretches are equally important because tightness in the calf muscles puts extra strain on the ankle. Stand facing a wall with your injured leg straight behind you, heel flat on the floor, and lean your hips forward until you feel a stretch. Hold 30 seconds, relax, and repeat for two sets of 10. Do a second version with the back knee slightly bent to target the deeper calf muscle.
Strengthening
Once you can walk comfortably, add strengthening work. Calf raises are the cornerstone: hold the back of a chair for balance and rise onto your toes, starting with both feet and eventually progressing to single-leg raises. Two sets of 10, six to seven days per week. For the smaller muscles of the foot, try picking up marbles with your toes and placing them in a bowl (20 repetitions), or scrunch a towel toward you using only your toes. These exercises rebuild the muscular support around the joint that the ligaments can no longer provide on their own while they’re healing.
Balance and Proprioception
This is the phase most people skip, and it’s the main reason sprains recur. When a ligament tears, it damages the nerve endings that tell your brain where your ankle is in space. Without retraining this sense, your ankle is far more likely to roll again. Start by standing on your injured foot with your eyes open, holding for 30 seconds. Progress to eyes closed, then to standing on an unstable surface like a pillow or wobble board. These drills should continue for weeks, even after pain has fully resolved.
Bracing and Taping for Return to Activity
When you return to sport or physical activity, external ankle support reduces re-injury risk. Research comparing lace-up braces to athletic taping has found that braces are slightly more effective, though both outperform no support at all. Braces also hold up better over time. Athletic tape loosens within 15 to 20 minutes of exercise and needs to be reapplied, while a brace maintains its support throughout a session. A lace-up or semi-rigid brace is the practical choice for most people during the months after a sprain.
Recovery Timelines
Grade 1 sprains generally heal in one to two weeks with consistent home treatment. Grade 2 sprains take longer, often four to six weeks before you can return to full activity. Grade 3 sprains, involving a complete ligament tear, can take several months, especially if surgery becomes necessary.
The biggest predictor of a slow recovery isn’t the grade of the sprain. It’s doing too little rehabilitation or returning to full activity too quickly. Skipping the balance training phase, in particular, leaves the ankle vulnerable. Roughly 40% of people who sprain an ankle go on to develop chronic problems, and inadequate rehab is a major contributing factor.
When Surgery Becomes an Option
Surgery is rarely needed after a first-time ankle sprain. It becomes a consideration when the ligaments have loosened or stretched to the point of chronic instability, meaning the ankle gives way repeatedly during normal walking or activity, sprains keep recurring despite rehabilitation, and persistent pain hasn’t responded to physical therapy or bracing.
Certain foot structures increase the risk of developing chronic instability: heels that tilt inward, high arches, or generalized ligament looseness from conditions like Ehlers-Danlos syndrome. The surgical procedure reconstructs the damaged ligaments on the outside of the ankle. Recovery from surgery itself takes additional months and involves its own rehabilitation program, which is why it’s reserved for cases where conservative treatment has genuinely failed.
