Sprains are injuries to the tough ropelike fibers (ligaments)that connect bone to bone. If you have a severe sprain, your symptoms maynot be much different from those you would have with a broken bone. Healthprofessionals rank sprains by degree of severity.

A first-degree sprain stretches the ligaments but doesnot tear them. Signs and symptoms may include:

• Mild to moderate swelling and pain.
• A stable joint that does not feel loose or wobbly.
• Normal movement.

A second-degree sprain partially tears the ligaments. Signsand symptoms may include:

• A pop or snap felt or heard at the time of the injury.
• Moderate to severe pain and swelling.
• Restricted movement.
• Bruising.
• Mild to moderate instability.

A third-degree sprain completely tears the ligaments. Signsand symptoms may include:

• A pop or snap felt or heard at the time of the injury.
• Mild to severe pain (pain is sometimes less in a completetear than in a partial tear).
• Severe swelling and bruising (often, but not always).
• An unstable joint (feels wobbly or loose).
• A grating sound or feeling.
• A bulge (sometimes) at the site of a complete tear.
• A change in sensation, such as numbness or tingling.

Recovery time for a sprain can vary, depending on a person'sage and health and the severity of the sprain. A minor sprain in a healthyperson may heal in a few days to a few weeks. A severe sprain can take severalmonths to heal and may never heal completely, resulting in long-term pain,limited movement, deformity and instability of the joint, and repeated injuries.

First aid for a sprain includes rest (immobilization),ice, compression, and elevation. While a minor sprain will often heal wellwith home treatment, a moderate to severe sprain may require medical treatment,such as a cast or splint, physical therapy, medication, or surgery.
