Hi joliejacq,
What you described and how you get it to leave, sounds like inverse psoriasis. Its, pink or red or even tan, blotchy or sometimes oval or round shaped. Its flat, not raised and itches and/or burns. Its treated with cortisone creams or ointments.
I was diagnosed with psoriasis, 2 years ago. Mine started with itching, redness and burning in the vaginal area. No gyno could find anything wrong with me. I had this on and off for almost 3 years, when finally, the psoriasis showed itself first in the groin area and areas below the waste..then it move along to other areas of the body and scalp where some comes and goes..and some sticks around. Inverse psoriasis is one type. The type that one gets in skin folds like groin, underarms, under breast and in overweight people, anywhere the skin might create a fold.
I had absolutely NO idea that I had psoriasis, nor that there were several types, and it seems neither do some gynos, because they saw it..and had no idea of what it could be.
I thought I would mention this..just to make you aware of it. By the way, I have seen most pictures of it, out there on the net. By looking at those, I could have never diagnosed myself, because it doesnt really look like the rash that I get. Most show this light tan rash..and its not that color, its red or pink. Anyway, you might want to look into this and maybe see a dermatologist the next time it shows up. The cortisone they give for that is a tad stronger than what one gets over the counter..and it gets rid of it in a few days. It does eventually return..but, you wont have to cream yourself up daily.

I have the under-breasts rashes, and sometimes in the underarms, and on the pelvic area.
The only thing that seems to help is hydrocortisone cream. I have to apply it almost daily - what a pain!
