What is a common symptom of tendonitis?

A common symptom of tendonitis is pain and tenderness around a joint. This condition typically occurs due to overuse or repetitive strain on a tendon, leading to inflammation. The pain often worsens with movement or activity that involves the affected tendon, especially when performing actions that engage the associated joint.

While swelling can occur in specific areas associated with the tendon rather than the entire limb, and muscle spasms may happen in some injuries, they are not defining characteristics of tendonitis. Difficulty in movement can be present as a result of pain but is not as direct a symptom as tenderness and localized pain. Therefore, the key indicators of tendonitis are primarily centered around pain and discomfort in the area surrounding the inflamed tendon.
