Pressure

I've been dealing with atmospheric pressure. Yesterday I started to get a headache. I took one of my prescription migraine pills and was OK. Today it started again, but not like one of my migraines. I also felt briefly light headed. I was going to try an OTC allergy pill, but saw it expired in 2005. Now I almost feel like I'm underwater...with a headache coming on. Maybe the rain will help. I blame it on the weather.
