I have been in Brazil for the past 2 years and I developed an armpit rash
, actually, it was a rash that started out around the buttocks, stomach, thighs and looks just like a pimple, red, itchs like crazy and with a yellow watery center. I was given a cream called Bi-Nerizona and it makes it go away within 3-4 days. It has now returned under my left armpit and if I stop using the cream, it will come right back, however, not itchy as before. What the heck is it?
