Most ankle sprains heal well with sensible early care and a structured rehab programme. The catch is that many people sprain the same ankle again, usually because the pain settled before strength and balance fully returned.
At Tylurs com, our physiotherapists see sprains from the sports pitch, the running track and the kerbside. This guide explains what happens inside your ankle, how to care for it in the first few days, when you need an X-ray and how rehab lowers your risk of doing it again.
Key takeaways
- A previous sprain is one of the biggest risk factors for the next one.
- The Ottawa ankle rules help decide who needs an X-ray; not every sprain does.
- Balance and strength training, not just rest, is what prevents repeat sprains.
- A crack, a misshapen ankle or being unable to take four steps needs medical assessment.
Common symptoms of an ankle sprain
Most sprains happen when the foot rolls inwards. Typical signs include:
- Pain on the outside of the ankle
- Swelling that builds over a few hours
- Bruising around the ankle or foot
- Pain when you put weight on the foot
- Stiffness and reduced ankle movement
- A feeling that the ankle might give way
What happens when you sprain your ankle
A sprain is an injury to a ligament, the tough bands that hold bones together at a joint. Most ankle sprains happen when the foot rolls inwards, stretching or tearing the ligaments on the outside of the ankle. Less often, the inner ligaments are injured, or the “high ankle” ligaments that bind the two shin bones together, which usually take longer to recover. Jumping, landing and quick changes of direction carry a higher risk, as do uneven ground and a previous sprain.
Ankle sprain grades
Clinicians grade a sprain from 1 to 3 depending on how much of the ligament is damaged. Swelling can hide the grade at first, so a clearer picture often comes four or five days after the injury.
| Grade | What has happened | Typical signs | Rough return to normal activity |
|---|---|---|---|
| 1 (mild) | Ligament stretched, small tears | Mild pain and swelling, able to walk | About 1 to 2 weeks |
| 2 (moderate) | Partial tear | Moderate swelling and bruising, painful walking | About 3 to 6 weeks |
| 3 (severe) | Complete tear | Marked swelling, hard to bear weight, ankle may feel loose | About 6 to 12 weeks or longer |
These ranges, from the StatPearls clinical review of acute ankle sprain, are only a guide; returning to high-level sport usually takes longer than returning to everyday walking.
Do you need an X-ray?
Emergency clinicians use the Ottawa ankle rules to decide who is likely to have a fracture. An X-ray is usually recommended if you have pain around the ankle or midfoot and:
- you could not take four steps, both straight after the injury and when examined
- the back edge or tip of either ankle bone is very tender to press
- the bone at the base of the little toe, or the inner midfoot, is very tender
These rules are a clinical tool, not a self-diagnosis test. If you are unsure, NHS guidance is clear: get it checked by a doctor.
The first few days
For the first two to three days, the NHS advises protecting the ankle, resting it from exercise, using ice wrapped in a towel for up to 20 minutes every two to three hours, a compression bandage and elevation, and avoiding heat, alcohol and massage. The PEACE & LOVE framework from sports medicine researchers builds on this: protect and elevate early, then let pain guide a gradual return to loading, keep fit with pain-free cardio and start exercise early. Our guide to ice or heat for an injury explains where each fits.
How physiotherapy helps an ankle sprain
A good programme does far more than wait for the ligament to heal. At the Tylurs com sports physio clinic, we check ligaments, movement, strength and balance, compare both ankles and build a plan around your goals.
Settling swelling and restoring movement
Early on we use compression, elevation, gentle foot pumping and a safe amount of walking. Sprained ankles often lose the ability to bend upwards, affecting stairs, squatting and running, so joint mobilisation is paired with home exercises.
Balance and strength
Ligament injuries disturb proprioception, your sense of where the joint is, which is one reason sprains recur. Training progresses from standing on one leg to eyes closed, unstable surfaces, then reaching, catching and hopping. We also strengthen the calf, the muscles on the outside of the lower leg and the hips; weak hip control can contribute to knee pain too. Brushing your teeth on your injured leg is an easy daily habit.
Returning to sport
The final stage rebuilds hopping, landing and cutting at speed. Through our sports injury rehabilitation service, strength and hop comparisons with your other leg guide when you are ready, rather than a fixed date. A lace-up brace or tape can add protection in the first year, but neither replaces rehab.
Preventing a repeat sprain
Some people develop chronic ankle instability: an ankle that gives way repeatedly and feels unreliable on uneven ground. To lower the risk:
- carry on with balance and strength work for several weeks after the pain has gone
- increase running volume and intensity in steps
- keep a short routine of single-leg balance, hops and calf raises two or three times a week
- consider a brace for higher-risk sport
Returning underprepared also makes other injuries, such as a hamstring strain, more likely. Heel pain that follows a sprain may involve plantar fasciitis, which the Tylurs com team can assess at the same visit.
When to seek urgent medical help
Go to an emergency department if you heard a crack, the ankle has changed shape, or your foot is numb, pale, blue or cold. Contact a doctor the same day if you cannot take four steps, ankle or foot bone is very tender to press, or pain and swelling are getting worse. After reduced walking, a painful, swollen, warm calf needs urgent assessment for a blood clot.
Book ankle sprain physiotherapy
Whether your sprain happened yesterday or your ankle has felt unreliable for years, we can assess it and give you a clear, staged plan back to the activities you enjoy. You can also browse other conditions we treat.
Book your ankle assessment and take the first step towards a stronger, more stable ankle.
Ankle sprain: frequently asked questions
Should I walk on a sprained ankle?
If you can walk without severe pain, gentle walking usually helps once the first day or two have passed. Let comfort guide how much you do, using crutches briefly if you are limping badly. If you could not take four steps after the injury, or ankle bone is very tender, get checked for a fracture.
How long does a sprained ankle take to heal?
Many mild sprains feel much better within two weeks, but the ligament keeps remodelling for longer. The NHS advises avoiding strenuous exercise for up to eight weeks, and severe sprains can take several months. Balance and strength usually lag behind pain, so finish your rehab even after the ankle feels normal.
How can I tell if my ankle is sprained or broken?
The two can look alike, with pain, swelling and bruising in both. A fracture is more likely if you heard a crack, cannot take four steps, the ankle looks misshapen or specific points of bone are very tender. If unsure, get it checked by a doctor or urgent care service, who can decide on an X-ray.
Why does my ankle keep giving way?
Repeated giving way after a sprain often signals chronic ankle instability: stretched ligaments, weaker muscles and reduced joint position sense, which slows your reactions on uneven ground. A structured balance and strengthening programme helps most people. If instability continues despite good rehab, your physiotherapist may suggest a specialist opinion.
