“Golfer’s elbow” is a condition of the tendons that causes pain on the inner side of one’s elbow, where the flexor tendons of one’s forearm muscles attach to the humeral supracondylar, and it usually occurs among golfers, but athletes in sports such as tennis, badminton, table tennis, and baseball, who use their arms to swing, or even those who often lift heavy objects, are prone to suffer from this injury.  Before the 2012 London Olympics, Dr. Chen conducted physical rehabilitation therapy for several months on the famous national badminton player Fu Haifeng for his golfer’s elbow.
