Fibromyalgia Review: Remembering What it is and Differentiating What it is Not

1.1. Introduction: Fibromyalgia has become the catch-all disorder for unexplained pain syndromes. As a result, many other disorders (e.g., Ehlers-Danlos Syndrome/Hypermobility Spectrum Disorder) have been misdiagnosed and, as a result, mismanaged. Fibromyalgia is a defined Rheumatological disorder characterized by chronic pain from 11 of 18 tender points typically bilateral and above and below the diaphragm lasting more than 6 months. 1.2. Methods: We studied 418 patients previously diagnosed with Fibromyalgia, who presented to five suburban autonomic clinics. All patients submitted to Parasympathetic and Sympathetic (P&S) monitoring as part of the standard of care in these clinics and treated for P&S dysfunction and pain as diagnosed. Data were compiled under HIPAA regulations and statistical analysis performed in SPSS v27.
