I spent a long time in the E.R. last night with another allergic reaction. We didn't get home until 5 a.m. this morning. We have no idea what caused the reaction. This is not uncommon for me. While there, I had my medications through the IV and when I received the liquid Benadryl, I got very light headed and couldn't breathe. I sure hope I'm not allergic to Benadryl. It's my life-saver. It's bad enough I'm allergic to Prednisone. That was the anaphylactic reaction in November. So today I'm recuperating.
