Any Doctors or experienced R.N.'s ?

Has anyone heard of a case like this? Last Oct, I took a prescription medication (for gerd) at night.The next morning around 10:30 am my throat started to feel heavier and tighter. It gradually got worse to the point I barely walk because I was loosing my breathe. I went to the E.R. and was a given Solu Medrol shot.The strange feeling went away and then later that night I started breaking out in hives but no other symptoms. The next afternoon same thing happened with my throat and I was red from my waist down. I went to a different E.R. and same thing they gave me a Solu Medrol shot again. After that day I was so sick I didn't know if I was coming or going. I was so weak, I could barely walk, oh and I covered in hives.This lasted for 4 weeks.I was supposed to take prednisone but by this time I said "to hell with it." I went to my GP and he couldn't figure it out, only said my white count was elevated ( but it wasn't ) that high. Went to an allergist he was thinking I had actually an allergy to a food instead of that actual medication. Since then I have been fine. I took everything out of my diet and over a period of six months gradually put everything back in. The only time get hives is if something scratches my skin but no allergy to anything. The only time I was been sick like this before was when I had a bad reaction to epstein t-bar and was in the hosp for 1 week ( something like bunch of lymph nodes in abdomen. Since then I have Splenomegaly, last year it was noted again during an ultrasound. But other than that healthy as a horse. Just being hopeful so next time I can nip this in the bud.
