Unlike tennis elbow, it happened on the tendon that located the inner side of the elbow, usually happens on pronator teres, flexor carpi radialis. Sometimes it also happens on palmaris longus, flexor carpi ulnaris, and flexor digitorum superficials.
Not only golf player will suffer this problem. Any activities that repetitive strains the muscle around the elbow will cause it.
