Most sprained ankles heal with a combination of short-term protection, early movement, and progressive strengthening exercises. Mild sprains typically take one to two weeks to heal, while a complete ligament tear can take several months. The specific steps you take in the first few days, and how you rebuild strength afterward, make a real difference in how quickly you recover and whether the ankle stays stable long-term.
Know What You’re Dealing With
Not all ankle sprains are the same, and your recovery approach depends on severity. A Grade 1 sprain involves no actual ligament disruption, just minimal swelling and little trouble bearing weight. A Grade 2 sprain means the ligament has been stretched without tearing, with moderate swelling and bruising. A Grade 3 sprain is a complete ligament tear, with severe swelling, bruising, and significant pain when you try to stand.
One useful way to tell whether you might have a fracture rather than a sprain: if you have point tenderness along the back edge of the bony bumps on either side of your ankle, or if you couldn’t take four steps right after the injury, an X-ray is warranted. These are the Ottawa Ankle Rules, a well-validated screening tool used in emergency departments. If you can walk four steps (even with a limp) and don’t have tenderness right on the bone, a fracture is unlikely.
The First 1 to 3 Days
The older advice of rest, ice, compression, and elevation (RICE) has been updated. A newer framework called PEACE and LOVE, published in the British Journal of Sports Medicine, covers both the acute phase and longer-term recovery. Here’s what the first few days should look like:
Protect the ankle briefly. Limit movement for one to three days to reduce bleeding inside the joint and prevent further damage to injured fibers. But don’t rest longer than necessary. Prolonged immobilization weakens the tissue. Let pain be your guide for when to start moving again.
Elevate. Keep the ankle above your heart whenever you can. This helps fluid drain away from the swollen area. The evidence behind elevation isn’t strong, but there’s virtually no downside.
Compress. Use an elastic bandage or compression wrap to limit swelling. Compression after an ankle sprain has been shown to reduce swelling and improve quality of life during recovery.
Skip anti-inflammatories for the first three days. This one surprises most people. Inflammation is part of how your body repairs damaged tissue, and suppressing it too early with ibuprofen or similar drugs may actually slow healing, especially at higher doses. The NHS guidance is straightforward: avoid NSAIDs for the first three days after a soft tissue injury. If you need pain relief to move around, acetaminophen (paracetamol) is a better choice during this window, since it reduces pain without interfering with the inflammatory repair process.
Rethink ice. Despite how common icing is, there’s no high-quality evidence that it helps soft tissue injuries heal. Ice may provide temporary pain relief, but it can also disrupt the blood vessel growth and immune cell activity your body needs to repair the damage. If you do ice, use it sparingly and primarily for pain control rather than as a healing strategy.
Start Moving Early
Once the initial pain settles (usually within a few days for mild sprains), the goal shifts to loading the ankle. This doesn’t mean pushing through sharp pain. It means adding gentle movement and weight-bearing as soon as your symptoms allow. Mechanical stress on healing ligaments actually promotes better repair and remodeling through a process where physical force stimulates cells to rebuild stronger tissue.
Passive treatments like ultrasound, electrical stimulation, and manual therapy early after injury have shown insignificant effects on pain and function compared to simply getting active. An active approach to recovery consistently outperforms passive one.
Rebuilding Range of Motion and Strength
A structured exercise program should continue for four to six weeks, performed three to five days per week. The American Academy of Orthopaedic Surgeons recommends targeting the calf muscles, shin muscles, and the smaller stabilizing muscles that run along the outside of the lower leg and the bottom of the foot. Here’s how a typical progression works:
Start with range-of-motion exercises. Trace the alphabet with your foot, or gently move the ankle up and down and side to side. Towel stretches (looping a towel around the ball of your foot and pulling gently) and heel cord stretches help restore flexibility in the calf and Achilles tendon. Aim for two sets of 10, nearly every day.
Once range of motion improves, add strengthening. Calf raises are a staple. You’ll likely start on two legs, gradually shifting more weight onto the injured side until you can do full single-leg calf raises. Rolling a golf ball under your foot and doing towel curls (scrunching a towel with your toes) rebuild the small muscles in the foot itself, which play a bigger role in ankle stability than most people realize.
Balance Training Prevents Re-Injury
This is the most overlooked part of ankle sprain recovery, and arguably the most important. When you sprain your ankle, you don’t just damage the ligament. You also disrupt the nerve endings that tell your brain where your foot is in space. This sense, called proprioception, is what keeps you from rolling your ankle on uneven ground. Without rebuilding it, you’re significantly more likely to sprain the same ankle again.
A good progression for balance training starts simple and gets harder over several weeks. During weeks one through four, practice short foot exercises while seated, pressing the ball of your foot into a slightly unstable surface. By weeks five through eight, progress to standing on both feet on an uneven surface. The end goal is a confident single-leg stance on the injured side, ideally by weeks five through nine.
Single-leg balance holds are one of the best exercises you can do. Stand on the injured foot for 20 to 30 seconds, three to five repetitions, almost daily. Once that feels easy, try it on a pillow or folded towel, or close your eyes. A mirror can help because visual feedback reinforces the brain-ankle connection you’re rebuilding. The Star Excursion Balance Test, where you stand on one leg and reach the other foot in multiple directions, is both a useful training exercise and a way to track your progress.
When to Use a Brace or Tape
As you return to sports or activities that involve cutting, jumping, or uneven terrain, external support helps. Studies comparing lace-up ankle braces to athletic taping have generally found that braces are slightly more effective, but both are better than no support at all. Taping loosens over the course of activity, while a brace maintains consistent support.
A lace-up brace is also more practical for most people since you can put it on yourself and reuse it. Consider wearing one during higher-risk activities for several months after the sprain, even once the ankle feels fine, since the ligament tissue is still maturing and your proprioception may not be fully restored.
Recovery Timelines by Severity
A Grade 1 sprain with minimal swelling and no ligament disruption typically heals in one to two weeks. You can often return to normal activities quickly, though balance training should still continue for several weeks.
A Grade 2 sprain, where the ligament has been stretched, generally takes four to six weeks before you’re back to full activity. Rehab exercises are essential during this period, not optional.
A Grade 3 sprain involving a complete tear can take several months. Some complete tears require immobilization in a walking boot, and a small number may need surgical repair, particularly in competitive athletes or when the ankle remains unstable after a full course of rehabilitation.
What Happens If You Don’t Rehab Properly
About 10% of people who sprain their ankle go on to develop chronic ankle instability. This happens when the damaged ligament heals in a lengthened position, leaving the joint looser than it should be. The ankle feels like it “gives way” during everyday activities, not just sports. Repeated episodes of giving way lead to more sprains, which further stretch the ligament, creating a cycle that becomes harder to break over time.
The most effective way to prevent this is the balance and strengthening work described above. The people who skip rehab and simply wait for the pain to go away are the ones most likely to end up with a chronically unstable ankle. Even after the exercises feel unnecessary, continuing them two to three times per week as a maintenance routine provides long-term protection.
