Minor daily living activities, e.g. opening door lock, heavy lifting, etc., would be greatly affected due to pain or decreased joint range of motion.

Consequence: If osteophytes irritate nearby nerve roots, blood vessels or other soft tissues, pain, numbness and muscle atrophy would be resulted.

Cause: prolonged and repetitive wrist and elbow movements would cause inflammation of tendons around the elbow joint.

Tennis elbow introduction: Tennis elbow refers to tendinitis over lateral epicondyle of elbow joint. Treatment effects depends on the stage of pathology development. Generally, the earlier the treatments start, the more obvious the prognosis would be.
