The elbow consists of a complex set of joints: these made up of bones, cartilage, ligaments and fluid. Muscles and tendons help the elbow joints to move. When any of these structures is injured or diseased, you have elbow problems.
Many things can make your elbow hurt. A common cause is tendinitis, an inflammation or injury to the tendons that attach the muscle to the bone. Tendinitis of the elbow is extremely common among sportspeople and manual workers. The most common cause is an overuse syndrome related to excessive wrist extension.
Other causes of elbow pain include sprains, strains, fractures, dislocations, bursitis and arthritis. Treatment depends on the cause.
