Well, first I started out with bug bites which I assume were fleas because I have cats, so naturally the itched and I wasn't worried about it, but then after I gave in to scratch them they bled a lot and even after they scabbed over they itched so badly that I couldn't help but scratch them. And then last night small little raised bumps appeared around the bites, even the ones that I had not scratched. They can't be bug bites because I have not been around any animals for over a week and all of my bed sheets and clothes had been washed before I left home. These little bumps itch very badly and since they are right beside existing scabs I keep accidentally reopening the scabs. I'm really worried that I might be having some kind of allergic reaction or something worse. Please help!
