A 60-year-old woman presents with pain and swelling in her wrist that is worse when moving the joint. She has a history of rheumatoid arthritis. What might be the underlying condition?
In a patient with rheumatoid arthritis, these symptoms could indicate extensor tendonitis, an inflammation of the tendons that straighten the wrist and fingers. Inflammatory diseases like rheumatoid arthritis can often lead to secondary tendonitis due to persistent joint inflammation.
