Ankle sprains are so common that they get dismissed, and that is exactly why so many people end up with an ankle they roll repeatedly for years.
Grades and timescales
- Grade 1 — a few ligament fibres damaged. 4–6 weeks.
- Grade 2 — a partial tear. 6–10 weeks.
- Grade 3 — a complete tear. 12 weeks to 6 months, needs medical assessment.
Get it x-rayed if you could not put weight on it at the time and cannot manage a few steps now, or if there is bone tenderness at the back edge of either ankle bone. Fractures are frequently mistaken for bad sprains.
Why they recur
A sprain damages more than ligament. It disrupts the position sense that tells your brain where the ankle is in space, and that does not come back on its own. Without retraining it, the ankle genuinely is less reliable afterwards — the warning system that would normally correct a roll is slower.
That is why balance work matters more than anything else here, and why the people who “just walk it off” are the ones who roll it again.
What treatment involves
Early on, settle the swelling and protect it. Then restoring the movement, because ankles stiffen quickly, and a stiff ankle changes how the knee and hip load above it.
Then the part that stops it recurring: balance and proprioception work, then strengthening. Simple, and routinely skipped.
