This article is about how a lot of people who have asthma, have attacks days after big thunderstorms. "The rainfall actually can break the pollens into smaller aero-allergens -- the pollen grains -- and this can actually exacerbate upper respiratory problems," says Dr. Shepherd. When I saw this article, I wanted to read it because before and after big thunderstorms I get really bad headaches. My father always told me it was because of the change of pressure that happens when storms come in.
