An ankle sprain needs to be examined if you cannot take four steps on it, if there is pain directly over bone, if swelling is severe, or if the ankle feels unstable. These signs raise the possibility of a fracture or a complete ligament tear.
Warning signs
Inability to bear weight. Tenderness on the bony bump on either side of the ankle or at the outer edge of the foot. Rapid, severe swelling. Numbness. A feeling that the ankle is loose or gives way.
Why it matters
Fractures, high ankle sprains, and tendon injuries are treated differently from a routine sprain. A sprain that heals without proper rehabilitation also raises the risk of chronic instability.
The first few days
Protect the ankle, use ice and compression, and elevate it. Start walking as soon as it is comfortable — early guided movement generally helps more than prolonged rest.
When a 'sprain' is not getting better
If you are still limping or swelling after four to six weeks, there may be a missed injury, such as a cartilage lesion or peroneal tendon tear.
