Final answer:
Tendinitis is inflammation of tendons due to overuse. Examples include tennis elbow and jumper's knee. Tendinitis can be diagnosed through a clinical examination and treated with rest and stretches.
Step-by-step explanation:
Tendinitis is the inflammation of a tendon that occurs due to overextension or excessive use of the joint without rest. It is commonly found in individuals whose jobs or hobbies involve repetitive movements. Examples of tendinitis include tennis elbow, golfer's elbow, jumper's knee, and swimmer's shoulder.
These are all overuse injuries that occur as a result of microtrauma to the tendons. Tendinitis can be diagnosed through a clinical examination, and in severe cases, X-rays may be used to rule out bone injuries. Treatment for tendinitis involves rest, cold compresses, and stretching exercises.
