Overview A sprain is a stretching or tearing of ligaments — the tough bands of fibrous tissue that connect two bones together in your joints. The most common location for a sprain is in your ankle. Initial treatment includes rest, ice, compression and elevation. Mild sprains can be successfully treated at home. Severe sprains sometimes require surgery to repair torn ligaments. Most ankle sprains involve injuries to the three ligaments on the outside of your ankle. Ligaments are tough bands of tissue that stabilize joints and help prevent excessive movement. An ankle sprain occurs when you roll, twist or turn your ankle in an awkward way. This can stretch or tear the ligaments that help hold your ankle bones together. Sprained ankle A sprained ankle is the stretching or tearing of ankle ligaments, which support the joint by connecting bones to each other. Signs and symptoms will vary, depending on the severity of the injury, and may include: • Pain • Swelling • Bruising • Limited ability to move the affected joint • Hearing or feeling a "pop" in your joint at the time of injury When to see the doctor Mild sprains can be treated at home. But the injuries that cause sprains can also cause serious injuries, such as fractures. You should see a doctor if you: • Can't move or bear weight on the affected joint • Have pain directly over the bones of an injured joint • Have numbness in any part of the injured area Causes A sprain occurs when you overextend or tear a ligament while s...
