Rotator Cuff Tear and Bicep Tendonitis
Rotator Cuff Tear
Rotator cuff tears affect the four tendons that are at the top of the humerus bone, where the joint attaches to the scapula (shoulder.) The actual tear happens when one of the tendons detaches from the bone, and can be caused by overuse over a period of time or an abrupt, jarring motion.
Bicep Tendonitis is the inflammation of the bicep tendon laying atop the humerus. It is very painful, and over time the inflammation can worsen, causing even more unbearable pain. This is caused by a repetitive overhead motion over time, as the joint becomes weaker and weaker.
