Final answer:
Repeated stress from activities like sports or certain jobs can cause tendinitis, which is the inflammation of a tendon. This condition causes pain and tenderness around the affected joint. It is usually diagnosed with a clinical exam and sometimes an X-ray, with treatment involving the PRICE protocol and NSAIDs.
Step-by-step explanation:
Repeated stress on muscles, joints, tendons, and delicate nerve tissues can cause a condition known as tendinitis. This is due to overuse or repetitive motion, resulting in microtrauma that ignites an inflammatory response within the tissue. Symptoms of tendinitis include pain, tenderness, and possible swelling around affected joints, and common types are tennis elbow, golfer's elbow, jumper’s knee, and swimmer’s shoulder. Diagnosis typically involves a clinical examination, and severe cases may be confirmed with an X-ray to rule out bone injuries. Treatment can involve the PRICE method (protection, rest, ice, compression, and elevation) and NSAIDs for inflammation and pain. In cases where the tendon has torn, surgical repair is required, which is painful given the slow healing nature of tendon connective tissue due to its poor blood supply.
