I don't know if you are still following this thread, but if you are, please make an appointment to get to your doctor and get an Epi-pen or two or three. There's no way to know if you'll ever need one, but if you do you'll need it very, very badly.
If your swelling on controlled by antihistamines, then great. You may want to add something like Tagament to it to completely shut down your histamine response. But if you have it under control you are blessed.
It's a PITA of a problem and some people with it (like me) can only be marginally controlled.
