I have red bumps on my groin, lower abdominal area, and armpits. The bumps on my groin tend to itch, especially in the morning. The bumps themselves are fairly good size, resembling mosquito bites. I now have smaller bumps that are beginning to appear on my stomach, chest, and down the insides of my arms. I was hoping to find out what this "rash?" is, or if it could be anything else.
