1980 Model of MSK Pain Nociceptive Neuropathic Primarily due to inflammation or tissue damage in the periphery Damage or entrapment of peripheral nerves. NSAID/Opioid Responsive Responds to both peripheral and central pharmacotherapy. Responds to procedures. Does not respond to procedures. Behavioral factors minor.

2017 Model of MSK Pain Nociceptive Neuropathic Central Primarily due to inflammation or tissue damage in the periphery Damage or entrapment of peripheral nerves. Primarily due to a central disturbance in pain processing. NSAID/Opioid Responsive Responds to both peripheral and central pharmacotherapy. Tricyclic neuro-active compounds. Opioid unresponsive. Responds to procedures. Does not respond to procedures. Behavioral factors minor. Behavioral Factors Prominent. Examples: Osteoarthritis, Rheumatoid arthritis, cancer pain. Examples: Diabetic peripheral neuropathy, post-herpetic neuralgia. Examples: FMS, cLBP, cHA, IBS. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1829161/
Comorbid Pain in FMS is the Norm “Overwhelming evidence reveals that what is often labeled as a single chronic regional pain syndrome is, upon closer evaluation, a chronic illness beginning much earlier in life, where the pain merely occurs at different points of the body at different points in time and is given different labels by subspecialists focusing on “their region” of the body.” Daniel Clauw, MD Low Back Pain https://www.ncbi.nlm.nih.gov/pubmed/22364327

Prescribers are Poor at Diagnosing Central Pain Syndromes “You cannot guess at the extent of fatigue, unrefreshed sleep, cognitive problems, multiplicity of symptoms, and extent of pain without a detailed interview. The new criteria obligate you to pay careful attention to the patient if you want to diagnose fibromyalgia.” Fredrick Wolfe https://www.ncbi.nlm.nih.gov/pubmed/20461781
Diagnosing Central Sensitivity Spectrum Disorders Pain in many body regions. 2. Higher current and lifetime history of chronic pain in several body regions. 3. Multiple somatic symptoms (e.g., fatigue, memory difficulties, sleep problems, mood disturbance) 4. Negative Affect, dispositional pessimism, pain catastrophizing. (Stable trait vs transient state) 5. More sensitive to other sensory stimuli (e.g., bright light, loud noises, odors, other sensations in internal organs) 6. 1.5 to 2x more common in women. 7. Strong family history of chronic pain. 8. High self-reported pain & distress (VAS/NPS/PSD/PCS) 9. Pain triggered or exacerbated by stressors. 10. Peak prevalence of FMS age 30-59 (working-age).* 11. Essentially normal physical examination +/- diffuse tenderness. https://www.ncbi.nlm.nih.gov/pubmed/26266995

Why Is Dx’ing FMS/CSS Important? It is opioid unresponsive. Once opioids are started FMS/CS patients are exquisitely sensitive to withdrawal symptoms & thus hard to taper. Guessing at the Dx makes for poor inter-rater reliability. Prognosis: Untreated it does not improve with time. When present amid other CNP conditions – HA, LBP, etc. – it is likely to be the primary source of morbidity. Patient expectations for treatment are often unrealistic. Provider satisfaction/comfort with care is low.

Sample Case
Joyce Joyce is a 45y/o woman who recently moved from CA to Jackson, County to retire. Her past medical history is significant for a work related back injury for which she was medically retired. She now receives SSD and seeks to establish care with you for primary care needs as well as pain management. Her medication regimen consists of Lisinopril for HTN. She is requesting “Percocet” for pain.
