Hi @jeffrapp...Do you live in Arizona? I ask because I also have an appointment in October with a neurologist at Phoenix Neurological Associates in Phoenix. It is interesting in that they have two clinical trials going on for idiopathic SFPN. One, as I recall, is being done in conjunction with with Harvard University...I'd like to get in on the trial but have been waiting months to get in there to just see a Dr..must be a lot of folks out there with neurological problems in the Phoenix area! Pam.
