The severe headaches EVERY day. that the doctor was sure were not...

I have migraines almost every day, usually when there is a strong change in air pressure due to storms. I live in Viet Nam and have been on Warfarin for a year and a half. The migraines are mostly blind headaches, without too much pain, but sometimes, the pain is very strong.
I fractured my skull in 14 places many years ago, and I think maybe there is a relationship between the fractures, the warfarin, and the dramatic weather differences here daily.
I used to go through phases of the headaches after moving to a different climate, then it would go away, but it doesn't seem to go away here.
