Golfer's elbow is a painful condition that causes pain due to inflammation on the inner side of your elbow (medial epicondyle). This is the area where the tendons of your forearm muscles attach to the bony bump on the inside of your elbow. While making a golf swing, the tendon is stressed, especially if a non-overlapping (baseball style) grip is used. The anterior forearm contains several muscles that are involved with flexing the fingers and thumb, and flexing and pronating the wrist.
You don't have to play golf to get Golfer's Elbow. Other names are Pitcher's Elbow, Climber's Elbow, and Little League Elbow….. any sport where the finger and hand grip is intensive. Overuse of the muscles and tendons of the forearm and elbow are the most common reason people develop golfer's elbow. Repeating some types of activities over and over again can put too much strain on the elbow tendons. These activities are not necessarily high-level sports competition. Shoveling, gardening, and hammering nails can all cause the pain of golfer's elbow. Swimmers who try to pick up speed by powering their arm through the water can also strain the flexor tendon at the elbow.
