A positive tennis elbow test indicates a sterile inflammation of the lateral epicondyle of the humerus, or a strain or injury to the muscle junction of the lateral epicondyle of the humerus. For example, lifting and carrying heavy objects with excessive force may cause damage to the epicondyle of the humerus and the muscle junction, and frequent heavy lifting or constant force on the outside of the forearm may cause excessive strain on the epicondyle of the humerus and the muscle junction, resulting in a chronic aseptic inflammatory lesion. These conditions are usually caused by cold in the elbow joint, as the muscle tissue itself is more tense after cold exposure. If there is a lot of force or constant fatigue, chronic damage is likely to occur, leading to the gradual formation of inflammation. Therefore, the first thing to do is to keep the elbow joint warm and not to get cold, and to keep the forearm and elbow joint fully relaxed and rested. It is also important to keep the forearm and elbow joint fully relaxed to help recovery from injury.
