Sprain: First Aid

By Mayo Clinic Staff

Your ligaments are tough, elastic-like bands that connect bone to bone and hold your joints in place. A sprain is an injury to a ligament caused by tearing of the fibers of the ligament. The ligament can have a partial tear, or it can be completely torn apart.

Of all sprains, ankle and knee sprains occur most often. 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.
Follow the instructions for R.I.C.E.

Rest the injured limb. Your doctor may recommend not putting any weight on the injured area for 48 hours, so you may need to use crutches. A splint or brace may also be helpful initially. But don't avoid all activity. Even with an ankle sprain, you can usually still exercise other muscles to minimize deconditioning. For example, you can use an exercise bicycle with arm exercise handles, working both your arms and the uninjured leg while resting the injured ankle on another part of the bike. That way you still get three-limb exercise to keep up your cardiovascular conditioning.
Ice the area. Use a cold pack, a slush bath or a compression sleeve filled with cold water to help limit swelling after an injury. Try to ice the area as soon as possible after the injury and continue to ice it for 15 to 20 minutes, four to eight times a day, for the first 48 hours or until swelling improves. If you use ice, be careful not to use it too long, as this could cause tissue damage.
Compress the area with an elastic wrap or bandage. Compressive wraps or sleeves made from elastic or neoprene are best.
Elevate the injured limb above your heart whenever possible to help prevent or limit swelling.

As the pain and swelling improve, gently begin using the injured area. You should feel a gradual, progressive improvement. Over-the-counter pain relievers, such as ibuprofen (Advil, Motrin IB, others) and acetaminophen (Tylenol, others), may be helpful to manage pain during the healing process. It's essential to restore strength and stability to the injured limb prior to a return to sports or fitness activities. A physical therapist or other sports medicine provider can provide you with the appropriate strength and stability exercises to optimize healing and minimize the risk of repeat injury.

See your doctor if your sprain isn't improving after two or three days.
Get emergency medical assistance if:

You're unable to bear weight on the injured leg, the joint feels unstable or numb, or you can't use the joint. This may mean the ligament was completely torn. On the way to the doctor, apply a cold pack.
You develop redness or red streaks that spread out from the injured area. This may mean you have an infection.
You have re-injured an area that has been injured a number of times in the past.
You have a severe sprain. Inadequate or delayed treatment may contribute to long-term joint instability or chronic pain.
