I have an itchy redish rash with little bumps (the bumps are now in little patchs) that started in my left armpit. It continued for a few days before it spread to my right armpit. I have been using Cortizone to help the itching but usually it burns when I first apply it. (I think it burns because I have scratched it) It seems to be spreading slightly.
I also wanted to point out that I have had a cold throughout the time I have had this rash.
Also the rash seem to be only on the armpit area.
What can I use to treat something like this?
Is there something that could help flush out whatever toxins are causing this?
