Widespread Pain, Incidental MRI Findings, and a Surgical Recommendation
Mrs. K is a 44-year-old woman with 3 years of diffuse pain involving the neck, shoulders, low back, and hips. She reports fatigue, nonrestorative sleep, and difficulty concentrating. Pain is 7/10 at rest and worse with light touch. She has seen four specialists. Lumbar MRI shows a 3-mm L4-L5 disc bulge and mild facet arthropathy; a spine surgeon recommends L4-L5 fusion. Examination shows widespread tactile allodynia, no weakness, normal reflexes, negative straight-leg raise, and 14 of 18 tender points. She is on no opioids and wants 'the cause' fixed. Inflammatory markers and thyroid tests are normal.
1. How would you distinguish nociplastic pain from neuropathic pain and from lumbar radiculopathy in this patient? Identify specific history and examination findings that support your formulation.

Neuropathic pain requires a plausible nerve lesion and a compatible distribution, often with burning, shooting pain and sensory loss or hyperalgesia in that territory. Radiculopathy would follow a dermatome or myotome, with weakness, reflex change, or positive tension signs. Here the pain is diffuse across neck, shoulders, low back, and hips, not limited to L4-L5; strength and reflexes are normal, straight-leg raise is negative, and allodynia is widespread. The MRI shows only a 3-mm bulge and mild facet change, which are common and do not explain diffuse pain. The combination of fatigue, nonrestorative sleep, cognitive difficulty, and widespread tactile allodynia supports nociplastic pain, such as fibromyalgia. Tender points are supportive but not required. I would use a symptom-based assessment and avoid anchoring on the MRI.
2. What is the role of the MRI findings, and how would you counsel her about surgery?
Read the worked answer
The MRI findings are common incidental degenerative changes and do not establish a surgical pain generator. A 3-mm disc bulge without concordant radicular symptoms, weakness, or reflex change is not an indication for fusion. Surgery addresses structural compression, not centralized or nociplastic pain, and fusion could add risk without improving her diffuse symptoms. I would explain that the scan shows mild wear-and-tear, not a dangerously damaged spine, and that her widespread pain likely reflects altered pain processing. I would avoid saying the pain is 'all in her head.' Instead, explain that nerves and brain processing can become sensitized. Offer a multidisciplinary plan and a second opinion if she wishes, but document that she has no progressive neurologic deficit and no surgical emergency.
3. Outline a first-line non-opioid treatment plan with measurable goals.

Start with education about nociplastic pain and set functional goals, such as walking 20 minutes five days per week and sleeping at least 6 hours. Recommend graded aerobic exercise and physical therapy rather than bed rest. Add cognitive behavioral therapy or pain psychology for coping and sleep. For pharmacotherapy, consider duloxetine 30 mg daily titrated to 60 mg, or amitriptyline 10 mg at bedtime if anticholinergic risk is low; avoid opioids and minimize sedatives. Treat sleep with sleep hygiene and, if needed, a non-benzodiazepine approach. Reassess at 4 to 6 weeks for function, sleep, and pain interference rather than pain score alone. If she is no better, reassess the diagnosis and consider a multidisciplinary pain program. Document that surgery was not recommended because findings do not match her symptoms.
