Skin rash (PUPPS?)

I recently came down with a rash on my belly and on my breasts. It started out of nowhere. It's small red bumps and they are all over the trunk of my body. They're extremely itchy!! They seem to be worse at night. Was curious if anyone had first hand experience with PUPPS and what they did to relieve the symptoms. I'll obviously call my dr tomorrow but I was just looking for some other opinions. Thanks!
