Your shoulder has the widest range of motion of any joint in your body. This flexibility allows you to do everything from throwing a baseball and swinging a tennis racket, to lifting and moving equipment.

The shoulder is a complex joint with several layers, including bones, ligaments, tendons, and muscles.

Common shoulder problems include dislocation, separation, bursitis, and rotator cuff tear.

Do you spend your days using a computer, sorting mail or assembling small parts? If your workplace duties put stress on your wrists, you may be at risk for carpal tunnel syndrome.

Common hand problems include arthritis, carpal tunnel syndrome, and ganglion cysts.

Cubital tunnel syndrome feels similar to the pain that occurs from hitting the "funny" bone in your elbow.

This disease usually begins with a thickening of the skin in the palm of the hand. This may develop into a hard lump or thick band that eventually causes the fingers to contract.

The pain of tennis elbow is caused by damage to the tendons that bend the wrist backward away from the palm.

Tendonitis is an inflammation of a tendon—the tough cord of tissue that connects muscles to bones. Tendonitis can affect any tendon, but is most commonly seen in the wrist and fingers.

The shoulder joint is the most frequently dislocated major joint of the body—often caused by a significant force that separates the shoulder joint's ball away from the joint's socket.

It might not make much of a storyline on a TV medical drama, but ankle sprains are one of the most common reasons for an emergency room visit.

Heel pain has many possible causes. Learning about the symptoms can help you take care of your heels and prevent problems.

Foot pain is often caused by improper foot function. Improperly fitted shoes can worsen and, in some cases, cause foot problems.

The goal of surgery is to relieve pain and correct as much deformity as possible. The surgery is not cosmetic and is not meant to improve the appearance of the foot.

RLS is a collection of symptoms generally described as unpleasant sensations and an urge to move the lower legs.

Stretching can keep your lower legs limber and your joints pain free.

If you are having problems with back pain, shin splints, knees or hips, look to your feet. Although these ailments might seem totally unrelated to one another, they can sometimes be linked to problems that start with your feet and how they're built, foot experts say.

Active women are at least twice as likely to suffer serious knee injuries as men, but it's not just athletes who are at risk.

The ACL is most often stretched or torn (or both) by a sudden twisting motion -- when, for example, your feet are planted one way and your knees are turned another.

Knee injuries account for 25 percent of all sports-related injuries, but proper conditioning can help prevent them.
