It is also called lateral epicondilytis. It is a pain focused on the outside of the arm, where your forearm meets your elbow. When you constantly use your arm in a repetitive motion, the tendons at the elbow end of a certain muscle -- the extensor carpi radialis brevis (ECRB) muscle --- may develop small tears. Tennis elbow affects up to 3% of the population, particularly adults between 30 and 50 years of age. But, less than 5% of cases are linked to tennis.
WHAT CAUSES TENNIS ELBOW?
It is a repetitive stress injury to the muscle. Any activity like hitting the ball back hand in tennis, too tight a grip on the racket, or any jobs or activities that involve repetitive arm motion, such as:
Tree-cutting (repetitive use of a chain saw)
Playing some types of musical instruments
WHAT ARE THE SYMPTOMS?
Commonly a soreness develops on the outer elbow and as it gets worse the pain may be unbearable to the point of not been able to pick up anything with that arm.
WHAT IS THE BEST TREATMENT? Prolotherapy treatment produces great results even in cases of refractory Tennis elbow that have not responded to other therapies. Cortisone injection can makes matters much worse. Remember that the problem here is a small tendon tears and cortisone weakens the tendons even more and can lead to complete rupture of the tendon.
