Thanks @rwinney...is your SFPN idiopathic? All I have is a biopsy report. I have not seen a real Dr yet (podiatrist only who I still believe are not real Drs and he is basically doing nothing than trying to give me $2,500.00/treatment Exosome injections. I declined as he claims this will regenerate the nerves but if I have SFPN the nerves will only be destroyed again if, for example, I have an autoimmune or genetic cause of the condition... SFPN is not a foot problem, it is a neurological problem that affects other parts of the body. So basically I have not seen a real Dr yet...my experience with Drs is limited so I figure go for the best if possible, Pam
