I have most of the same symptoms but I’m not dx’d with Fibromyalgia. I have Small Nerve Fiber Polyneuropathy. Small nerve fibers are everywhere in our bodies. In our skin they are responsible for sending heat, cold and pain signals to our brain. When they get diseased it can cause Allodynia which presents with skin hypersensitivity, exaggerated cold, heat or pain sensations and excessive sweating—hyperhydrosis. When the small nerve fibers in the bones or bone marrow get diseased it can cause the terrible deep aching bone pain. Tinnitus, eye problems, digestion—slow motility, belly bloat, constipation and bladder function are all symptoms of this disease. Small Nerve Fiber Polyneuropathy or Small Nerve Fiber Neuropathy with Autonomic Involvement can cause Positional Orthostatic Tachycardia Syndrome (POTS) which can give you dizziness and palpitations and vertigo upon standing. A recent study showed that nearly 50% of Fibromyalgia patients had Small Nerve Fiber Neuropathy. The best way to determine SNFN is via punch biopsy.
