Ankle sprains occur when the ankle is twisted or forced in a way that stretches or tears one or more ligaments. The severity of the injury depends on if the ligaments are stretched, partially torn, or fully torn.

Symptoms of an ankle sprain include pain, bruising, swelling, stiffness, and difficulty walking.

Prompt medical attention is highly recommended. If left untreated, or if treated incorrectly, ankle sprains can heal incorrectly, which can lead to chronic problems.

Nonsurgical treatment includes R.I.C.E. (rest, ice, compression, elevation), nonsteroidal anti-inflammatory medications (NSAIDs), and physical therapy.

In severe cases, surgery may be recommended in order to repair a torn ligament.
