I too, like many others have very bad allergies, what I call the works,the only thing I dont seam to be allergic to are animals, and I dont have food allergies, but,
2 of my 3 children do, my daughter is so allergic to poison Ivy,when it germanates or polenates, she breaks out, we would use an oatmean bath, put oatmeal in a stocking with warm water bath, this also helped her Egzama, and we used Benadril, my son is allergic to insect bite, he also gets benadril, hydraquatazone, and lots of water for both to help flush out the toxins in there skin,
While they were both babies we found out they are allergic to milk, so we tryed, Soy Milk, or Goat Milk, they like goat milk the best, and its good for many other reasons....

I hope this helps or gives you some ideas
Blessings**
