HI, in December if 1999 I broke out in a horible case of hives from my head to my toes. I was outside. It's now 2001 and everytime I step outside if I'm out longer then 20 minutes I break out in terrible hives that cause me to hypervinilate and my heart rate is inormous. I've been tested for all allergies and I have none. I had an AND test done for lupus and it came back negative. Another thing that triggers it is water. I haven't been able to shower or take a full bath since 1999. I have to wash with a wash tub and wash cloth. I can't figure out whats wrong with me but I feel like I'm dying! PLEASE HELP!
