Hi, I've been having this rash on my armpit, it got pretty bad and now it seems like it's starting to maybe go away, however, it's appearing on the other one now. It itches really bad. It's like these little red bumps that show up and then sometimes form into blisters. At first I thought it may have been this new deoderant i've been using, but I quit using it and it has since gotten worse. Any help will be greatly appreciated.pit.jpg
