One day about a month ago, I noticed a rash on my right shin. It didn't itch, and it started out pale. Now, these red dots have appeared all over my body, mostly on my stomach, lower back, front pubic area and the backs of my thighs. It itches from time to time, but it didn't itch at first. I assume the reason it's itching now is because each red patch has become very dry and scaly.
The red splotches are slightly raised, yet flat. They are dry, flaky, and the same shade of red all the way through. I've included pictures of my stomach and back for reference.
I went to a doctor a couple of weeks ago and he said he was almost positive it was an allergic reaction to something. I got a steroid shot and was prescribed Prednisone and Allegra, both of which have not helped me and now the rash is worse than ever. This leads me to believe that either 1) this is not an allergy rash or 2) I keep coming into contact with whatever it is that I'm allergic to, without knowing.
I know people can develop allergies naturally over the course of their lives, but I just want to know if anyone has any ideas as to if it is indeed an allergy rash or if it looks like something else.
If you have any insight at all, please reply. I feel disgusting when I look in the mirror, and I'd really like to get rid of this as soon as possible. Thanks in advance.
