Which chronic condition is characterized by widespread pain, tenderness, fatigue, and sleep disturbance?

• A. Fibromyalgia
• B. Osteoarthritis
• C. Tendonitis
• D. Rheumatoid arthritis

Answer: (A)

Widespread pain with tenderness, fatigue, and sleep disturbance points to a centralized pain syndrome. Fibromyalgia is a chronic condition where pain is amplified by the central nervous system, leading to widespread musculoskeletal pain that lasts for months, along with fatigue and nonrestorative sleep. It’s not driven by inflammation in joints or tendons, which helps distinguish it from other conditions.

Osteoarthritis involves degenerative changes in joints and typically presents with localized joint pain and stiffness, often with imaging findings. Tendonitis is localized to a specific tendon and painful with movement of that tendon. Rheumatoid arthritis is an autoimmune inflammatory disease with joint swelling and stiffness and abnormal inflammatory labs. The combination of widespread pain, fatigue, and sleep disturbance without inflammatory joint disease makes fibromyalgia the best fit.
