Hi,
yeah, I just posted a few minutes ago, about having to go to the ER yesterday, for something very similar. YOu didn't say anything about breathing problems like I had, but yes, HORMONES CAN CAUSE UNBELIEVABLE THINGS! I also have noticed, since May, that a lot of things get worse before my period, about 5 days before. I get vaginal itching, sorness, stinging in there, and just plain feel very anxious as well. I imagine hormones can trigger allergies as well !
