A 35-year-old woman presents with 6 months of diffuse musculoskeletal pain, fatigue, and difficulty sleeping. She reports tender points in her neck, shoulders, and hips. Physical exam reveals multiple tender points on palpation without objective joint swelling or inflammation. Laboratory tests, including CBC, ESR, CRP, and thyroid function tests, are all within normal limits. What is the most likely diagnosis?
✓ Correct Answer: Option C
Fibromyalgia is characterized by chronic widespread pain, fatigue, and tender points on physical examination. The absence of objective inflammation and normal lab tests help distinguish it from other rheumatic conditions.
