Tennis Elbow (or lateral  epicondylitis) affects nearly half of all tennis players at some point. Tennis actually account for less than 5 percent of all reported cases.

Golfer’s Elbow (or medial epicondylitis) is similar to tennis elbow but pain and tenderness are felt on the inside (medial aspect) of the elbow, on or around the joint's bony prominence.

Symptoms Of Tennis Elbow

• Recurring pain on the outside of the upper forearm just below the bend of the elbow; occasionally, pain radiates down the arm toward the wrist.
• Pain caused by lifting rotating or bending the arm or grasping even light objects such as a coffee cup.
• Difficulty extending the forearm fully (because of inflamed muscles, tendons and ligaments).
• Pain that typically lasts for 6 to 12 weeks; the discomfort can continue for as little as 3 weeks or as long as several years.
