Arthritis can result from traumatic events such as fractures or injuries to the ligaments. Osteoarthritis results from wear and tear along with the aging process. Symptoms include swelling around the joint, cyst formation, pain with motion, stiffness, and subluxation or instability in the joint. Carpenters, roofers, painters, and mechanics frequently suffer from this malady. The muscle strains eventually can cause small tears in the tendon.
Scar tissue forms as the tears begin to heal.
As they start to heal, more tears occur. Overuse eventually will cause weakness and inflexibility in the muscles of the forearm specifically the wrist extensors. Symptoms include pain and tenderness over the lateral aspect of the elbow and often times in the muscles on the top part of the forearm. Pain in experienced mostly in hitting a backhand stroke in tennis or with gripping and resisted movements at the wrist. Attempting to generate all force from the wrist and forehand rather than proper stoke production involving the whole body, with legs flexed, full hip rotation into the ball and weight transfer into the forward leg.
