Rolling an ankle is one of the most common injuries there is. It happens stepping off a curb, landing from a rebound in basketball, on an uneven trail, or on a patch of black ice in January. Because it is so common, it is often treated casually: limp for a week, wait for the swelling to go down, and carry on.
The problem is that a significant proportion of sprained ankles never fully recover. People go on to sprain the same ankle again, experience it 'giving way', or have lingering pain and swelling for months. This article explains how to manage a sprain well from the first day, when you need an X-ray, and the rehabilitation that prevents the next one.
What happens when you sprain an ankle
The vast majority of ankle sprains happen when the foot rolls inward and the sole turns to face the other foot. This stretches or tears the ligaments on the outside of the ankle, most commonly the anterior talofibular ligament, which is the weakest of the group. Bigger forces may also injure the calcaneofibular ligament below it.
Sprains are graded by severity. A grade one sprain is a stretch with microscopic tearing; grade two is a partial tear with more swelling and some looseness; grade three is a complete tear with significant swelling, bruising and instability. A less common 'high ankle sprain' injures the ligaments that bind the two lower leg bones together. It typically takes longer to recover and benefits from early identification.
Do you need an X-ray? The Ottawa Ankle Rules
The Ottawa Ankle Rules were developed by emergency physicians in Ottawa and are now used around the world to decide who needs an X-ray after an ankle injury. They reduce unnecessary imaging while reliably picking up fractures. An X-ray is indicated if there is pain in the ankle or midfoot area and any of the following.
- Inability to bear weight and take four steps, both immediately after the injury and at assessment.
- Bone tenderness along the back edge or tip of the outer ankle bone.
- Bone tenderness along the back edge or tip of the inner ankle bone.
- Bone tenderness at the base of the fifth metatarsal, the bump on the outer edge of the midfoot.
- Bone tenderness over the navicular bone on the inner side of the midfoot.
Other reasons to see a doctor
Seek medical care for a deformed-looking ankle, numbness or a cold, pale foot, an open wound, severe pain that is not controlled with simple measures, or calf pain and swelling in the days after injury, which can occasionally indicate a blood clot. A sudden 'pop' at the back of the ankle with difficulty pushing off can be an Achilles tendon rupture, which needs prompt assessment and is often mistaken for a sprain.
The first few days
Early management has moved away from complete rest. The aim now is to protect the ankle while getting it moving as soon as pain allows. Ice and elevation can help with comfort and swelling in the first days. Compression with a tensor bandage or sleeve reduces swelling. A brace or lace-up support is often more useful than a tensor alone for moderate sprains, because it allows walking while protecting the ligaments.
Walking as normally as pain allows, with crutches briefly if needed, is encouraged. Gentle range-of-motion exercises, such as tracing the alphabet with your toes or pumping the foot up and down, can begin within the first day or two. For most grade one and two sprains, early functional treatment like this leads to faster return to work and sport than immobilisation in a cast. Severe sprains are sometimes protected in a boot or brace for a short period.
Why rest alone isn't enough
After an ankle sprain, the ligaments heal, but other changes linger unless they are addressed. The small sensors in the ligaments and joint that tell your brain where your foot is are disrupted, so your balance and reaction time on that side are poorer. The muscles around the ankle, especially those on the outer leg that resist rolling, are weaker and slower to react. Ankle stiffness, particularly in bending the foot upward, alters how you walk and land.
This combination explains why people who have sprained an ankle once are at higher risk of doing it again, and why some develop chronic ankle instability — repeated giving way and a feeling that the ankle cannot be trusted. Rehabilitation is what restores these functions, and it is far more effective at preventing the next sprain than rest or taping alone.
Rehabilitation, stage by stage
A typical programme progresses through overlapping stages. The timing depends on the severity of the sprain and how you respond.
| Stage | Focus | Example exercises |
|---|---|---|
| Early (days 1–7) | Protect, control swelling, restore movement | Ankle pumps, alphabet tracing, walking as tolerated |
| Intermediate (week 1–3) | Strength and balance | Calf raises, resistance band eversion, single-leg stance |
| Advanced (week 3–6+) | Power, agility, sport-specific control | Hopping, lateral bounds, cutting drills, unstable surfaces |
| Return to sport | Confidence and full function | Sport drills at full speed, single-leg hop tests |
Balance training: the most important part
If you do only one thing after an ankle sprain, make it balance training. Programmes of balance and coordination exercises have been shown to reduce the risk of re-spraining substantially. The exercises are simple and can be done at home.
Start by standing on the injured leg for 30 seconds, near a counter for safety. Progress by closing your eyes, standing on a pillow or folded towel, turning your head, catching a ball, or reaching in different directions with the other leg. Continue for several months after the ankle feels normal; the protective effect builds with consistent practice.
Returning to sport and activity
The absence of pain is not the same as readiness. Before returning to sports involving running, jumping and changes of direction, you should be able to hop repeatedly on the injured leg without pain, balance on it as well as on the other side, and perform sport-specific movements at full speed with confidence. Many athletes use a brace or tape for six to twelve months after a sprain as an additional safeguard, particularly in high-risk sports such as basketball, volleyball and soccer.
A mild sprain may allow return within one to two weeks. Moderate sprains commonly take three to six weeks, and severe sprains or high ankle sprains can take several months.
When an ankle doesn't settle
If your ankle is still painful, swollen or unstable six weeks or more after a sprain, it is worth having it reassessed. Persistent problems can mean an injury to the cartilage of the ankle joint, a tendon injury, a missed fracture or a high ankle sprain. Ongoing giving way suggests chronic instability, which usually responds to a dedicated rehabilitation programme and only occasionally needs surgical repair.
Footwear and winter ankles
Ontario winters add their own risks. Icy driveways, slushy curbs and uneven packed snow are behind a large share of the sprains we see between December and March. Boots with a firm heel counter and good tread, ice cleats for walking on untreated surfaces, and taking shorter, flatter steps on slippery ground all reduce the chance of a roll. In warmer months, worn-out running shoes with a collapsed outer edge and high, narrow heels are common contributors. If you have sprained an ankle before, footwear that holds the heel securely matters more than cushioning.
