Question:
A patient presents with widespread pain and multiple comorbidities. Which of the following clinical scenarios is most consistent with fibromyalgia?
A patient presents with widespread pain and multiple comorbidities. Which of the following clinical scenarios is most consistent with fibromyalgia?
Show Hint
To distinguish Fibromyalgia from Polymyalgia Rheumatica (PMR): Fibromyalgia has normal ESR/CRP, tender points all over, and no response to steroids. PMR has highly elevated ESR/CRP, proximal muscle stiffness, and an incredibly rapid, dramatic response to low-dose steroids.
Updated On: Sep 3, 2026
- Pain sensitization increased by sleep disturbances with multiple comorbidities
- Pain worsened by activity without any systemic features
- Pain with swelling and stiffness
- Joint pain with prompt response to NSAIDs

The Correct Option is A
Solution and Explanation
Concept:
Fibromyalgia is a chronic, non-inflammatory pain syndrome characterized by widespread musculoskeletal pain, fatigue, sleep disturbances, and cognitive dysfunction. The core pathophysiology is driven by central nervous system sensitization (altered pain processing).
Explanation:
• Fibromyalgia involves augmented central processing of pain (central sensitization). Patients experience hyperalgesia (increased pain response to painful stimuli) and allodynia (pain response to non-painful stimuli).
• Sleep disturbances (non-restorative sleep, alpha-delta sleep anomaly) are both a hallmark symptom and an aggravating factor. Poor sleep directly lowers the pain threshold and worsens central sensitization.
• Fibromyalgia is frequently associated with multiple comorbidities, including irritable bowel syndrome (IBS), chronic daily headaches/migraines, interstitial cystitis, and mood disorders (depression/anxiety).
• Option (B) is incorrect. Pain worsened purely by activity without systemic features is characteristic of osteoarthritis or mechanical musculoskeletal conditions. Fibromyalgia has profound systemic features (fatigue, brain fog).
• Option (C) is incorrect. Objective joint swelling (synovitis) is absent in primary fibromyalgia. If objective swelling is present, an inflammatory arthritis (like RA or Lupus) must be evaluated.
• Option (D) is incorrect. Fibromyalgia pain originates centrally, not from peripheral tissue inflammation. Therefore, it typically has a poor or minimal response to NSAIDs. Drugs targeting CNS neurotransmitters (SNRIs like duloxetine, or gabapentinoids like pregabalin) are preferred.
Final answer:
Central pain sensitization exacerbated by non-restorative sleep and accompanied by overlapping functional somatic syndromes (comorbidities) accurately describes Fibromyalgia.
