I have had similar symptoms while I during that 30 minute wait Judy mentioned. They take it seriously!! I had a baby sitter for about 2 hours. It turned out that I had a chronic infection that was keeping me in yellow zone, but the doctor wanted me getting my shots. The first time it happened someone had sprayed Lysol in the rush waiting room right behind me. I left the waiting room for after my first shot, but stayed in it after my second shot. The two things combined was trouble. The nurse actually caught that one before I did because my complexion was bad. It hasn't happened since I was treated for the infection though.
However, I created a browser buttun to my region. This site is useful to me year round since I have year round pollen allergies. It is also useful to those of you who suffer mold allergies since they also count that.
