I was wondering what you do to get rid of the migraines triggered by the change in barometric pressure?

Be vigilant: This is common. Some migraineurs would make great weatherpeople; they can predict a cold front 3 days in advance without any silly Doppler radar. Mainly women, I don't know why. It helps not to wait till the headache arrives. Try treating as soon as you feel the "hovering" feeling migraineurs describe. Work out a stepwise system with multiple meds.
