Elbow pain is most often the result of tendinitis, which can affect the inner or outer elbow. Tendinitis is inflammation, irritation, and swelling of a tendon, which is the fibrous structure that joins muscle to bone. In many cases, tendinosis (tendon degeneration) is also present. Tennis elbow (lateral epicondylitis) and golfers elbow (medial epicondylitis) are usually the result of repetitive overuse from work or playing a sport.
Hand or wrist problems can by caused by a variety of conditions, such as arthritis, carpal tunnel syndrome or thoracic outlet syndrome.
