Medical Rationale
Fibromyalgia is among the most common and well-documented manifestations of Gulf War Illness (GWI), a presumptive condition under 38 CFR § 3.317 for Gulf War veterans. GWI and fibromyalgia share central sensitization as the core pathophysiological mechanism: chronic neuroinflammation from exposure to organophosphates, sarin, pesticides, and depleted uranium dysregulates central pain processing by permanently altering spinal cord dorsal horn wind-up mechanisms and reducing descending pain inhibition via the periaqueductal gray-rostral ventromedial medulla pathway. Research by Robert Baraniuk and others at Georgetown has documented neuroinflammatory cytokine elevation in cerebrospinal fluid of GWI patients, confirming the neuroimmune basis shared with fibromyalgia. Studies of Gulf War cohorts document fibromyalgia prevalence 2–4 times higher than matched civilian controls.

Filing Tips
Fibromyalgia may already qualify as a stand-alone presumptive under Gulf War illness provisions. However, if it is not yet service-connected, filing it as secondary to an already service-connected GWI-related condition provides an additional pathway. American College of Rheumatology 2010 diagnostic criteria (widespread pain index + symptom severity scale). Rheumatology records. Gulf War veterans should consult a VSO about both direct presumptive claims and secondary claims to maximize all available pathways. Fibromyalgia rated at 10–40% based on functional impairment and musculoskeletal examination findings.
