What is the most likely diagnosis for a 55-year-old female with widespread musculoskeletal pain and multiple tender points?

• A. Fibromyalgia
• B. Rheumatoid arthritis
• C. Reiter's syndrome
• D. Gouty arthritis

Answer: (A)

The most likely diagnosis for a 55-year-old female with widespread musculoskeletal pain and multiple tender points is fibromyalgia. This condition is characterized by chronic pain throughout the body, typically accompanied by specific tender points, along with symptoms such as fatigue, sleep disturbances, and cognitive difficulties often described as "fibro fog." The presence of widespread pain and tenderness – particularly in specific regions – aligns closely with the diagnostic criteria for fibromyalgia, which highlights these symptoms as central to the condition. In contrast, other conditions listed, such as rheumatoid arthritis and gouty arthritis, are characterized by specific joint involvement, inflammation, or other systemic symptoms that don’t primarily focus on widespread pain and tender points. Rheumatoid arthritis typically presents with symmetrical joint involvement and systemic signs of inflammation, while gout is characterized by acute episodes of joint pain usually involving a single joint and can be accompanied by signs of inflammation like redness and swelling. Reiter’s syndrome, or reactive arthritis, is often linked with infection and usually presents with joint pain alongside other systemic symptoms, such as eye inflammation or urinary problems. None of these other diagnoses capture the global and diffuse nature of musculoskeletal pain and tender points seen in this patient, making fibromyalgia the most fitting diagnosis.
