@amandajro Hello, Just joined this group today so thank you for the welcome. I was diagnosed with 'Small Fiber Neuropathy with Autonomic Involvement' in 2016. At least my neurologist's nurse said: "Your notes indicate this is the nearest diagnosis that matches your symptoms at this time". Since then, the stinging and burning pain is spreading from both buttocks (worst pain which prevents me from sitting for more than a few minutes and has destroyed my social life and travel) to all limbs, face and eyes. Regarding Sanexas Electrical Nerve Stimulation, a new clinic opened up in my area claiming it is a "new treatment for neuropathy. It is a more natural, non-invasive, painless and effective therapy. Instead of covering up the symptoms with harmful drugs that can lead to dangerous site effects, this cutting-edge approach focuses on healing the damaged nerve endings, Sanexas Treatment will work to stimulate the body's tissues at the cellular level. This treatment energizes the mitochondria and speeds up the healing process of the damaged nerves and the tissues surrounding them. Sanexas Treatment also increases the oxygenation of injured tissue as well as increases cellular function." I'm skeptical so ran it by my physician who said it looks reasonable but unlikely to help you but it won't hurt to give it a try so as they offer a free consultation I thought I would visit them and check it out.
