Golfer's elbow, also known as medial epicondylitis, is an overuse injury that occurs in the elbow. As its name suggests, it is very common in people who play golf. However, any type of repetitive elbow activity can cause medial epicondylitis. Golfer's elbow occurs when the tendons that attach your forearm muscles to the inside of the bone at your elbow become worn down and inflamed.
Pain from golfer's elbow is usually experienced on the elbow joint at the inside of the arm (where your elbow creases). Pain on the inside forearm is also common. If you were to rest your arm on a table, this is the area that is directly touching the surface. Patients may experience additional pain when carrying out certain actions, such as gripping an object, turning a doorknob, performing a swinging motion with the arm, or even picking something up. Other symptoms include stiffness, pain when making a fist, and weakness in the hands and wrists. In some cases, numbness or tingling may be present in the fingers.
