I too am in Canada, ottawa, ontario. Where are you?
I have suffered with continuous severe temporal headaches for twelve years now. Have tried everything possible and no results at all. The procedure you are referring to is an occipital nerve stimulator implanted. I still have not found anything of the sort in Canada so far but seems to me it must be done somewhere??? if you find out anything let me know and i will do the same.
I just read another thread, peteswife, who mentions nerve decompression surgery so i will research that as well.
What times of doctors have you seen, meds and treatments have you tried?
