My doctor prescribed me topamax today. I am already on amitriptylline 30mgs at bedtime for "migraines". I think my headaches are related to the chiari as dr shelat reproduced the pain when he put pressure on my head in a certain way. My current md said there is interaction between amitriptylline and topamax and also compazine which i take as needed. I do lortab for the pain, but i am afraid to take the topamax rx'd for "migraines" i don't think they are migraines. I was thinking i should call tci tomorrow and see if i could run this all by dr shelat or dr insigna. When i start the topamax he told me not to take compazine, but if i don't take the compazine i can't keep the lortab down and the last time this happened (before i had compazine to take) i ended up in the emergency room from vomiting all day every 1/2 hour. I know this is a lot of info, but i'm feeling lost. also the triptans don't work for me.
