I just recently had a T.R.U.E. test done. I found I was sensitive to many things. My Dr. said it was the worst reaction he had ever seen. I have a problems with Parabens, fragrances, caine mix, quaternium, formaldehyde and a couple of others. I don't have my list here. It has been about a month now since having the test and I still have red marks on my back. Anyway, my point is to make sure you eliminate outside irritants as your symptoms are similar to mine.
