In short
- Ameli, France’s health insurer, advises a medical exam within 24 hours if possible.
- A crack, a misshapen or numb ankle means A&E first, per the NHS.
- Ameli calls rehabilitation the first-line treatment for a sprain.
- Return to sport takes from 1 week to 3 months, depending on severity, per Ameli.
You twisted your ankle and it swelled up. This guide explains what a sprain is in plain words. It lists the signs that call for a doctor or an X-ray first. It then walks through the stages of rehab with a physiotherapist, and the return to sport. Every medical point comes from a public health body listed at the bottom.
A sprain is a ligament stretched too far or torn
Ameli, France’s public health insurer, defines an ankle sprain as an excessive stretch of one or more ligaments. It ranges from a simple stretch to a partial or full tear. It follows a sudden twist of the ankle.
The outer ligament is the one most often hurt. Ameli says an outer sprain without a fracture makes up 90% of ankle sprains. It describes three grades:
- mild: one band of the ligament is stretched, not torn, and the ankle still moves
- moderate: one band is torn, with sharp pain, swelling, bruising and trouble standing on it
- severe: two or three bands are fully torn, and the ankle is clearly unstable
Some signs mean emergency care before a physio
The NHS lists signs that may point to a broken bone. They need emergency care straight away:
- you heard a crack when you were injured
- the ankle has changed shape or points at an odd angle
- the area is numb, tingling or has pins and needles
- the skin around it has turned blue or grey, or feels cold
A doctor checks the ankle within 24 hours if possible
Ameli says it matters that a doctor examines you within 24 hours if possible. The diagnosis comes from questions and an exam of the ankle. The doctor may see you again after 3 to 5 days.
An X-ray is not routine. Ameli says X-rays are needed only when a fracture is suspected. The NHS also advises quick medical advice if you cannot walk more than a few steps.
Your doctor can then refer you to a physio. For costs, see our guide to physio session prices in Morocco.
Rehab moves from pain relief to a stable ankle
Ameli calls rehabilitation the first-line treatment for an outer ankle sprain. It starts early, after a first sprain or a repeat one. Ameli describes these stages:
- easing pain and swelling
- moving the ankle early and putting weight back on it, to avoid stiffness
- strengthening the muscles that keep the ankle stable
- in the last phase, working on stability and the reflexes that stop you rolling it
Return to sport depends on the grade, and a sprain can come back
According to the NHS, the first physio session starts with questions about your symptoms and lifestyle. The physio may check your strength and balance. They then give you an idea of how many sessions you may need. Ameli plans a check of the ankle at about 1 week, then about 3 weeks.
Ameli says return to sport takes 1 to 3 weeks after a mild sprain. It takes 4 to 6 weeks after a moderate one. A severe sprain needs 6 weeks to 3 months. The marker is an ankle with no pain and normal movement. The NHS adds that most sprains feel better after 2 weeks.
A sprain without proper rehab can come back. Ameli explains that the ankle may stay unstable, which leads to repeat sprains. Over the years, the risk is arthritis of the ankle.

Common questions
How many physio sessions does an ankle sprain need?
There is no single number for everyone. It depends on how bad the sprain is. Per the NHS, the physio gives you an estimate at the first session.
Do I need an X-ray for a sprained ankle?
Not always. Ameli says X-rays are needed only when a fracture is suspected. The doctor decides after the exam.
When can I return to sport after an ankle sprain?
Ameli gives 1 to 3 weeks for a mild sprain and up to 3 months for a severe one. The ankle should be pain-free and move normally.
Why do ankle sprains come back?
Ameli explains that an ankle without proper rehab can stay unstable. That instability leads to repeat sprains.
