Don't know but will check. My next appt is march 6th. My dr had mentioned before either a chiropractor or acupuncture but I'm not crazy about the latter. My sister-in-law had also mentioned seeing a nerve dr. My dr is a neuro. I've been seeing him since I was a teen (I'm 43 now) for seizures. He originally gave me the occipital nerve block for the headaches but that's no longer working. I'm sick of trying different meds that don't work. I don't know what else to do.
