I have a rash that started as itchy bumps in my armpit that I scratched. And then both armpits turned bright red extremely inflamed itchy, dry and edges were like flaky. I took prednisone which seemed like was making it fade. Then when the prednisone was done, it began to spread across my breasts and down my forearms turning the inside of my elbows bright red and inflamed. Now its spread down my forearms and my inner thigh and the creases of the back of my knees. Please help it itches and burns and though my armpit seems to be fading back to normal. ...now I have painful pimples in them and my arms have all these red dots/patches
