I woke up with bumps all over me

Patient: I woke up two days ago with five bumps on my face that resembled bug bites so i thought nothing of it. Then the second day I woke up and the bumps were all over my body from my Scalp Back Stomach Thighs. I went to the doctor and was prescribed some allergy medications Amoxicillin, Fluocinonide , Predisone. However when i got home after the doctors I noticed I had three bumps on my Gentitals aswell of the same sort. One on my penis and two on my Scrotem. Could it be something other than an allergy?
