What is a common symptom of tendonitis?

A common symptom of tendonitis is swelling and tenderness in the affected area. Tendonitis occurs when a tendon, which connects muscle to bone, becomes inflamed or irritated, usually due to overuse or injury. This inflammation leads to localized swelling, soreness, and tenderness, particularly when pressure is applied or during movement of the affected joint. Individuals may experience pain that can worsen with activity and improve with rest.

In contrast, improved range of motion, excessive joint stability, or the presence of a lump are not characteristic symptoms of tendonitis. Typically, tendonitis results in reduced range of motion due to pain and inflammation rather than improvement. Excessive joint stability is not associated with tendonitis, as it usually leads to decreased flexibility and potential weakness in the joint area. Lastly, while a lump may arise from other types of injuries or conditions, it is not a definitive symptom of tendonitis and does not typically present in cases focused on inflammation or irritation of the tendons.
