I have huge problems with barometric pressure changes as well. I can always tell when it's going to rain. And sometimes the barometric pressure changes are smaller, but I still feel a slight difference in symptoms with it, like an increase in sensitivity. My physical therapist said this could mean that there's rain in the next state over, for example, so there's still pressure changes but not something that we can observe with changing weather over our heads.

Moist heat seems to make a difference during this time. I never thought I'd be able to handle heat before I tried it at PT one time, but it has to be moist heat, not dry. I also can't do it if the burning is really bad at the time. It seems to help with sensitivity pain anytime too for a couple hours.
