Hey... I have been struggling with this issue for a couple of weeks now. I'm 22 years old, and I decided to change my deoderant. Within a coulple days I developed a rash that itched really bad. I bought some anti-itch cream hoping that would help, and then switched back to a deoderant that I knew had worked for me in the past. The itch never completely stopped, but did get a little better. Now I develop these pimples under my arms that are extremely painful. They are similar to ones that never come to a head but that stay under the skin. No matter what I do they dont go away. Currently I have about 6 under one arm, and dont know how to treat them, so that they wont come back. Please help!!!
