I went to the doctor when they first started to appear and they stated it was a rash and gave me some topical cream, which made the itching decrease, but did not make the sports go away. They then told me to use some cream that is used in the vaginal yeast infection kits, which helped the itching again, but did not make the spots go away. The itching finally ceased after a couple of weeks, but I'm left with the dark circle spots as a mark. Now new ones are starting to appear(very few though) and the old dark flat circles are starting to itch again(not all of them, but some of them are). They vary in size from small-medium-large. They are kinda rough looking. I also get these welps on my arm that flare up from time to time and then after about 30 seconds to a minute it goes away. I've went over in my mind if it could be I'm allergic to anything, but can find no cause. Because I have not changed any products or eaten any food I don't normally eat, and this all of a sudden just occured. My skin was fine 5 months ago. I don't want to go to the doctor again and get told some useless stuff that does not work. What is this and how to get rid of it for good?
