Carpal tunnel syndrome is when the median nerve is compressed as it passes through the carpal tunnel - an opening in your wrist that is formed by the carpal bones on the bottom of the wrist and the transverse carpal ligament across the top of the wrist.
Find out what to do if you have an injury to the elbow; bone, muscle, joint or ligament of the elbow; or have elbow pain - muscle pain caused by overuse (too much exercise or heavy lifting).
A fracture is a partial or complete break in the bone - either open (also called compound fracture; the bone pokes through the skin and can be seen, or a deep wound exposes the bone through the skin) or closed (also called simple fracture - the bone is broken, but the skin is intact).
Osteoarthritis (also called degenerative joint disease) happens when the cartilage in a joint becomes damaged and worn, usually due to age, wear and tear, overuse of the joint, or other problems.
Tennis elbow (lateral epicondylitis) is a form of tendonitis that occurs when the forearm muscles are used again and again in a twisting motion. Pain can spread into the forearm and wrist.
