Well, it could be allergies, too. Are you around any corn or bean fields? If there is harvesting going on that could do it. We are seeing alot of people with similar complaints in the clinic right now. Maybe a little echinacea is in order for you right now.
I think it has to with my sinuses...i have been having a lot of headaches, my throat has been swollen and sore, and ya thats all i can think of right now....
