What is a characteristic feature of rheumatoid arthritis?

A characteristic feature of rheumatoid arthritis is the stiffness and swelling of joints. This condition involves an autoimmune response that leads to inflammation in the synovial fluid of the joints, causing pain, tenderness, and swelling. Patients often experience morning stiffness that can last for several hours, significantly affecting their mobility and daily activities.

The inflammation associated with rheumatoid arthritis also contributes to joint destruction over time, making early recognition and management essential to prevent further complications. Stiffness persists after periods of inactivity, and the swelling is typically a result of synovitis, which is the inflammation of the joint lining. This distinguishes rheumatoid arthritis from other types of arthritis, where joint pain may be more localized or where swelling may not be a predominant symptom.

Understanding these features helps in diagnosing and treating rheumatoid arthritis effectively, guiding interventions that can manage pain and slow progression of the disease.
