Hello! I Have A Rash On The Upper Part Of

Hello! I have a rash on the upper part of my back, shoulder blade to shoulder blade, and also on my chest, underside of my breast to above my belly button. It is not bumpy. It is warn to the touch, my skin is raised, and it is very itchy. Painfully itchy. It feels and looks like a sunburn. I am currently taking minerals and enzymes to treat candida. That rash went away. Same feeling but that rash was blustery and bumpy. Maybe it's the same thing. Any ideas on what it could be our possible treatment. I don't know how much more of the pain and itching I can take.
