Sprained Ankle
DEFINITION
A sprained ankle is an injury that occurs when you roll, twist or turn your ankle in an awkward way. This can stretch or tear the tough bands of tissue (ligaments) that help hold your ankle bones together.
Ligaments help stabilize joints, preventing excessive movement. A sprained ankle occurs when the ligaments are forced beyond their normal range of motion. Most sprained ankles involve injuries to the ligaments on the outer side of the ankle.
Treatment for a sprained ankle depends on the severity of the injury. Although self-care measures and over-the-counter pain medications may be all you need, a medical evaluation might be necessary to reveal how badly you’ve sprained your ankle and to put you on the path to recovery.
CAUSES
A sprain occurs when your ankle is forced to move out of its normal position, which can cause one or more of the ankle’s ligaments to stretch, partially tear or tear completely.
Causes of a sprained ankle might include:
- A fall that causes your ankle to twist
- Landing awkwardly on your foot after jumping or pivoting
- Walking or exercising on an uneven surface
SYMPTOMS
Signs and symptoms of a sprained ankle include:
- Pain, especially when you bear weight on the affected foot
- Swelling and, sometimes, bruising
- Restricted range of motion
- Some people hear or feel a “pop” at the time of injury.
When to see a doctor
Call your doctor if you have pain and swelling in your ankle and you suspect a sprain. Self-care measures may be all you need, but talk to your doctor to discuss whether you should have your ankle evaluated. If your signs and symptoms are severe, it’s possible you may have broken a bone in your ankle or lower leg.
