I have fibro with vasculitis (including aneurysms)and get migraines triggered by high heat and high humidity. I have Darvocet for that but don't like to take it all the time-makes me too sleepy to work. I tried Excedrin Migraine last month and it knocks out the pain not only in my head but also in my shoulders from typing and my ankles, too. I have a bottle at my desk and take 2 when I feel the headaches coming on. Just a thought.
