Document Summary
What is it: also known as lateral epicondylitis, some muscles in your forearm attach to the lateral epicondyle, tennis elbow occurs when the tendon that attaches the muscle, the extensor carpi radialis brevis, gets damaged, although the name, lateral epicondylitis" suggests it is due to inflammation of the tendon, the injury actually occurs because of small, microscopic tears in the tendon, this injury usually happens due to overuse or a fall on the elbow. How does it happen: scientifically speaking, it happens because of repeated contractions of the muscle with little time to rest, whenever you use a tendon, there are always small traumas done to the respective area and in order to fix that, your body adapts by sending in regeneration mechanisms that help repair the area, that"s also why this injury mostly happens with older people because their body"s ability to regenerate tendons has depleted.
