The past month or two I have had a lot of itching around my mouth, face and my scalp and neck. This reaction was severe when I ate mango, but I stopped eating that and now it seems like it happens all the time regardless of what I eat. I ve gotten a rash on my neck that feels dry and its red and noticeable. The only medications I take are Zoloft and birth control, but ive taken these for a long time. A doctor I saw a few weeks ago gave me a steroid called prednisone and said it was some kind of fungus. That steroid did seem to help but it still doesn t tell me what I could be allergic to. Any help is much appreciated!
