Most mild ankle sprains feel noticeably better within about two weeks, but feeling better is not the same as being ready for sport. The NHS advises avoiding strenuous exercise such as running for up to eight weeks, and severe sprains can take months to return to normal. Balance and strength training during that time is what lowers the chance of the ankle giving way again.

How long does each grade of ankle sprain usually take?
Healing time depends mostly on how much ligament was stretched or torn. Clinicians often describe sprains in three grades, and the ranges below are typical, not promises. Your own timeline depends on the injury, your age and fitness, and how quickly you start moving and loading the ankle sensibly.
The NHS notes that most sprains and strains feel better after two weeks, that strenuous exercise such as running should be avoided for up to eight weeks because of the risk of further damage, and that severe sprains can take months. Pain usually settles well before the ligament has regained its full strength, which is why people who feel fine at two weeks still re-injure the ankle on a trail or court.
Indiana winters add their own hazard. An ankle that is only partly recovered in December has to cope with icy sidewalks and parking garage ramps, so plenty of people find that a sprain from the fall season gets tested again on the first freeze. Balance work done before the ice arrives pays off.
- Mild (grade 1): ligament stretched; walking within days, sport often within a few weeks.
- Moderate (grade 2): partial tear with more swelling and bruising; often several weeks to around two months before full activity.
- Severe (grade 3): complete tear; often several months, sometimes with a period in a boot.
- High ankle sprain: injury to the ligaments joining the two shin bones; usually slower than a typical sprain.
What should I do in the first 72 hours after rolling an ankle?
Protect the ankle, control swelling, and start gentle movement as soon as pain allows. Elevate it above heart level when resting, use ice in short spells for comfort, and use compression if it helps. Walking on it, with crutches or a brace at first if needed, is usually encouraged once you can bear weight, because early movement tends to speed recovery compared with long rest.
Get an X-ray or urgent assessment if you cannot put weight on the ankle or walk more than a few steps, if there is tenderness directly on the bones of the ankle or foot, if you heard a crack, or if the foot looks deformed, numb or discolored. Our comparison of physical therapy or urgent care for a sprained ankle explains which to choose.
Why does a sprained ankle sometimes take longer than expected?
Common reasons include returning to sport too soon, never retraining balance, a missed injury such as a high ankle sprain or small fracture, or a sprain on top of an ankle that was already loose from earlier injuries. Each of these can turn a few weeks into months of swelling, aching or giving way.
Repeated sprains can lead to chronic ankle instability, where the ankle feels wobbly or rolls with little provocation. If your ankle still swells after activity two to three months on, or keeps giving way, that is worth an assessment rather than more waiting. Our high ankle sprain page covers the slower-healing type.
How does rehab shorten the road back to sport?
Rehab restores the range, strength and balance that a sprain takes away, and those are what protect against the next sprain. AAOS OrthoInfo states that incomplete rehabilitation is the most common cause of chronic ankle instability after a sprain, and the 2021 clinical practice guideline on lateral ankle sprains from the Academy of Orthopaedic Physical Therapy covers both first-time sprains and the instability that can follow them.
A typical plan moves from regaining motion and walking normally, to calf and ankle strengthening, to balance and hopping, then to cutting and sport-specific drills. Simple balance work such as the single-leg balance exercise is usually part of it from early on. For youth athletes playing at Grand Park in Westfield, or adults returning to pickleball or basketball, the final stage includes the quick changes of direction the sport demands.
- Restore motion, especially bending the ankle upward
- Walk without a limp
- Rebuild calf and ankle strength
- Retrain balance on one leg, then on uneven surfaces
- Hop, land and cut without pain or hesitation
How do I know my ankle is ready for running or sport?
You are generally ready when you can walk and jog without pain or a limp, balance on the injured leg as well as the other, hop repeatedly and land steadily, and change direction at speed without hesitation. Swelling should no longer appear after activity.
A therapist can test these side by side and help you plan the step back into running or sport. To get started, see ankle sprain physical therapy or complete the physical therapy questionnaire, and the matching team will propose a therapist in the network.

Related questions
Should I walk on a sprained ankle?
Usually yes, once you can bear weight without severe pain. Use crutches or a brace for a few days if needed. If you cannot put weight on it or walk more than a few steps, get it checked for a fracture.
Do I need to wear an ankle brace after a sprain?
A brace can protect the ankle during the early weeks and when returning to sport. It works alongside rehab exercises, not instead of them.
Why is my ankle still swollen weeks after a sprain?
Some swelling after activity can linger for weeks. Persistent swelling beyond two to three months, or swelling with instability, is worth assessing.
Can a sprained ankle heal in a week?
A mild sprain can feel much better within a week, but the ligament keeps healing for weeks after. Return to sport gradually.
Is a sprain worse than a break?
Not always. A severe sprain can take as long as, or longer than, a simple fracture to recover from, which is why rehab matters for both.
