Neurological symptoms in legs and arms experiencing hyperesthesia (NOT painful) and sometimes numbness and erratic mild muscle pain. Fibromyalgia?

Probably not. Fibromyalgia is a specific condition that should only be diagnosed by an expert. FMG is associated with specific trigger points not general numbness & hyperesthesia. Unfortunately even health care professionals toss around the term Fibromyalgia leading to many missed diagnosis & 'therapeutic misadventures' (which can be deadly). See a neurologist, & then a FMG specialist if a diagnosis isn't made.
