Lateral epicondylitis or tennis elbow is a condition typically caused by the motion of a tennis down stroke. The muscle of the forearm becomes weak from overuse. As the elbow bends and straightens, the muscle rubs against bony bumps in the forearm, which can cause wear and tear of the muscle over time. When small tears form in tendon fibres that attach the muscle to the elbow, pain and swelling occur.
Tennis elbow pain is typically felt in the tendons of your forearm muscles, which are connected to the outside of the elbow. Likewise, pain can be felt in the forearm and wrist.
This condition can happen to anyone who uses their forearm muscles regularly. Tennis elbow pain is more often experienced by painters, plumbers, carpenters, cooks and butchers.
Depending on the severity of the condition, tennis elbow treatment consists of over-the-counter pain relievers, tennis elbow physiotherapy, and surgery.
