Tennis elbow is the common name given to a condition that brings about pain in the arm, where the forearm meets the elbow. The medical term is lateral epicondylitis. Tennis players are not the only people to commonly experience tennis elbow. Repetitive motion creates this condition, and stress of overuse, which leads certain muscles to develop small tears. Specifically at the end of the extensor carpi radialis brevis muscle, which connects to the elbow. The tendons and muscles in your forearm are under a lot of stress when you repeatedly strain them with a particular action. When they tear, it puts stress on the rest of your arm, the tendons become inflamed, and it may be painful to grip or lift objects.
Affecting up to 3% of the population, sufferers may develop symptoms such as an ache or pain in the elbow, a weakness in the arm and hand and it may be tender to touch. Treated with exercise, physical therapy, and some medications, tennis elbow can heal over time and rest.
