Can anyone help me figure out why I got an itchy rash on one lone spot on my body? I have been walking in the woods, but the spot is in an area that is always covered. It is under the bra area, on my left side, and just showed up out of the blue. I have tried treating it with hydrogen peroxide, baking soda, cortisone cream, and other such things, to no avail. I don't know if I should spend money I don't have to get it checked out. Any help??? Thanks.
