Abstract

Fibromyalgia has previously been categorized as primary, secondary, and juvenile fibromyalgia. However, these definitions do not adequately explain the etiopathology of disease, nor do they help direct new specific therapies. Herein, we review the previously known categorizations of fibromyalgia. Based on common patient characteristics and previously studied pathophysiologies, we propose new subcategorizations of fibromyalgia that we have self-narrated, including hormonal fibromyalgia, neuroendocrine fibromyalgia, psychologic fibromyalgia, inflammatory fibromyalgia, and lastly neuropathic fibromyalgia. To verify, add to, and fully describe these selfnarrated categories of fibromyalgia that we have proposed, future research needs to be done.

Keywords: Fibromyalgia, subcategory, primary, secondary, hormonal, inflammatory, juvenile, neuroendocrine.
