As far as I can remember the pain started when I punched a punching bag, it is on the back side of my elbow, elbow cap I guess for lack of a better term. but the pain went away in a few days.. It keeps reoccuring when I play sports like baseball and volleyball, but not everytime I play. should I look into buying a brace? also I was researching this problem and suggested treatments or preventions were, stretching before activities and strengthening surrounding muscles.. how do you stretch your elbow?? and what exercises do you perform to strengthen the target muscles??
