Hi...I'm trying to figure out what kind of rash this could be. It started off looking like little pimples. There were 3 together, and then a set of 2. They are painful if I touch them or try to squeeze them. They don't really itch unless I mess with them. I break out in hives often since I'm allergic to a lot of different things...but these don't look like the hives I get. I've had this for about a week now, but as time goes on, they are getting worse and more swollen like.
