Final answer:
Tennis elbow is a condition that occurs due to repetitive motion leading to tendon inflammation and pain near the elbow. Diagnosis is mainly through clinical examination, and treatment includes rest, medication, and potentially surgery for severe cases.
Step-by-step explanation:
Tennis elbow, also known as lateral epicondylitis, involves pain near the outside of the elbow and is a form of tendinopathy. This condition is commonly seen in individuals whose activities require repetitive motion, like playing tennis or engaging in certain jobs. The repetitive motion leads to microtrauma and an inflammatory response in the tendons.
Clinical examination is typically sufficient for diagnosis, but in severe cases, where pain is intense, X-rays might be necessary to exclude bone injuries. The connective tissue in tendons has a limited blood supply which results in slow healing, and if tendons are severely damaged, surgical repair may be required which is painful and necessitates a prolonged recovery period.
