Sprained ligaments often swell rapidly and are painful. Generally, the greater the pain and swelling, the more severe the injury is. For most minor sprains, you probably can start initial injury treatment yourself.

Do sprains always swell?

Although the intensity varies, all sprains commonly cause pain, swelling, bruising, and inflammation. The ankle is the most commonly sprained joint. And a sprained ankle is more likely if you've had a previous sprain there.

How long does a sprain stay swollen?

Typically, swelling will reside naturally within two weeks of the injury, even with more severe ankle sprains. If severe swelling occurs after this, you may want to consult your doctor for an ankle injury.
