Tendonitis, tendon, tenosynovitis, tennis elbow..

Tendonitis   Inflammation of a tendon due to irritation or overuse. The most common cause of tendonitis is repetitive actions which can create microtears in the collagen matrix structure of the tendon itself. The result is inflammation and weakening of the tendon. Tendonitis can be diagnosed by ultrasonography or magnetic resonance imaging. It is easy to detect in its early stages and difficult to treat in later stages. If tendonitis is detected early, it can be treated effectively by exercises, stretches and changes to the environment. Tendonitis self-help.
Tendonitis causes, symptoms and treatment.

Tendon   The fibrous cord of soft tissue that attaches a muscle to a bone.

Tenosynovitis   Inflammation and swelling of the tendon sheaths. The sheath, due to overuse, is unable to create enough lubricating fluid for the tendon. It usually occurs in the wrist or hand, potentially caused by repetitive movements such as very high-speed typing. Trigger finger - a form of tenosynovitis.

Tennis elbow   The medical term; "lateral epicondylitis" occurs when muscles and tendons in the elbow area are irritated, torn or damaged (the lateral epicondyle is the bony part that is on the outside of the elbow joint) The pain may be on the outside of the elbow or forearm and can be aggravated by bending the wrist back, turning the palm up, or by forceful gripping or squeezing.

Thoracic Outlet   Clinically it is the top of the ribcage with the first rib (left and right), the first thoracic vertebra and the manubrium (top of breast bone) as it's borders. The clavicle (collarbone) is often included in the definition of this area. See thoracic outlet syndrome for more.

Thoracic Outlet Syndrome(TOS)   is a group of distinct disorders producing signs and symptoms attributed to compression of nerves and/or blood vessels in the thoracic outlet region between the base of the neck and the armpit area. Symptoms of TOS usually include pain in the neck and shoulder area and numbness, coldness and weakness in the arm/hand. One common site for compression is between the anterior and middle scalene muscles of the neck. As the brachial plexus passes through this area, muscular tension can create an impingement affecting most of the arm. Another common site is between the clavicle and the first rib where vascular compression can also occur. Self-help for thoracic outlet syndrome
