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
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
Factors that increase your risk of a sprained ankle include:
Sports participation. Ankle sprains are a
common sports injury. Sports that require rolling or twisting your foot,
such as basketball, tennis, football, soccer and trail running, can
make you vulnerable to spraining your ankle, particularly if you're
overweight. Playing sports on an uneven surface also can increase your
risk.- Prior ankle injury. Once you've sprained your ankle, or had another type of ankle injury, you're more likely to sprain it again.
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.
