Most people who play sport roll an ankle at some point. Most of us shrug it off, hobble around for a few days, and get back to it. That’s also why it’s the injury most likely to happen again.
What actually happens when you roll an ankle
Most ankle sprains are on the outside of the ankle, where the ligaments are stretched or torn when the foot rolls inwards. Sprains are graded by how much damage there is:
- Grade 1: the ligament is stretched. Mild swelling and tenderness, and you can usually still walk.
- Grade 2: a partial tear. More swelling and bruising, noticeable pain walking, and some looseness in the joint.
- Grade 3: a complete tear. Significant swelling and bruising, and it’s hard or impossible to bear weight.
The first 48 to 72 hours
Current thinking has moved on from complete rest. A useful guide is the PEACE approach to the first days of a soft-tissue injury:
- Protect: limit movement and avoid aggravating activity for the first one to three days. Don’t immobilise it for longer than you need.
- Elevate: raise the ankle above heart height where you can.
- Avoid anti-inflammatories: these can help pain but may get in the way of tissue repair. Check with a pharmacist or your GP before taking them.
- Compress: tape or a compression bandage to control swelling.
- Educate: let your symptoms guide you rather than resting for weeks. Early gentle movement beats prolonged rest.
After that, the LOVE phase takes over: stay optimistic, get the blood flowing with pain-free exercise, and load the ankle progressively as pain allows. Guidelines for ankle sprains point the same way: they favour external support such as a brace or tape, progressively putting weight through the ankle, and early movement over prolonged immobilisation.
When to get it checked urgently
Most rolled ankles aren’t broken, but a few are. Get examined promptly if:
- you can’t take four steps, either right after the injury or when you’re assessed
- there’s tenderness directly on the bone at the back edge or tip of the ankle bumps
- there’s tenderness at the base of the foot on the outer side, or on the inner side of the midfoot
- you heard a pop, there’s obvious deformity, or swelling and bruising came up straight away
- you have numbness, or the foot looks pale or cold
These are the signs doctors use (the Ottawa ankle rules) to decide whether an X-ray is needed. They’re very good at ruling a fracture out.
How long does it take to recover?
Recovery depends on the grade, and on how well it’s rehabilitated. As a rough guide:
- Grade 1: often one to three weeks
- Grade 2: typically four to eight weeks of structured rehab
- Grade 3: several months, and sometimes a surgical opinion
“Back to walking” and “ready for sport” are very different milestones. An ankle that feels fine on a flat footpath can still be weak and slow to react when you cut, land or change direction.
What good rehab looks like
The aim isn’t just to get the swelling down. It’s to rebuild what the injury took away:
- Range and weight-bearing: walking normally again and getting full movement back, especially the ability to bend the ankle upwards
- Strength: the calf and the muscles on the outer side of the ankle, which help control rolling
- Balance and control: single-leg balance, then balance on unstable or moving surfaces
- Sport-specific work: hopping, landing, cutting and changing direction, progressed as the ankle tolerates it
- Objective checks before you return: comparing strength and hop performance with the other leg, rather than relying on how it feels. We measure calf and outer-ankle strength on VALD equipment, and the targets are on our strength standards page.
Why ankles keep rolling
A previously sprained ankle is the biggest risk factor for another sprain. Guidelines for people who’ve sprained an ankle before recommend two things: balance and control exercises, and wearing a brace or taping during sport. Both are aimed at reducing the risk of it happening again. Skipping rehab because the pain has settled is the most common way a one-off sprain turns into a recurring problem.
Where to start
If your ankle isn’t improving after a few days, keeps giving way, or you want a proper plan to get back to sport, sports physiotherapy is the right place to start. You don’t need a GP referral to book, and our referral guide covers the funding options. Once the ankle is settled, strength and conditioning and performance testing are how you check it’s truly ready, not just pain-free. Our ankle sprain page covers how we assess and treat them, and our sports injuries page covers other common injuries.
