I have tried nerve blocks other meds for migraines ect... I suffer everyday with head pain due to 17 cranial facial surgeries and 4 craniotomy's too. I am ready to get a new pain doctor! I think he experiments on me and has detoxed me 3 times and then I was in such head pain that I passed out. I have taken narcotics before and I feel if they watch and follow me then all should be well.?
