I have had a really bad allergic reation to something and I am trying to figure out what. I used Nairn hair removal cream a week and a half ago on my chin and I had an open pimple that it went on.When I wiped and washed the cream off my face was extremely itchy and small raised pimples started forming on my chin and down my neck. In the next day or so I had welts and rash all under both breasts and that then spread up between my breasts onto my chest. My doctor put me on predislone and antibiotics for the last 4 days and although it is much better in that area and my chin is completely fine, I have very red skin on my upper chest now with lots of lumps like bites which heat up and get really itchy and then subside. It look like bad heat rash or sunburn but it has all just been moving up through my body. I am now taking Pherergan but still itchy and hot. Could this all be from the hair removal cream. I am desperate, it is horrendous.
