It may be hives, which is frequently associated with an allergic reaction. Have you ever had hives before? How long has it been there now and have you tried taking something, like an antihistamine?
It is not hives because it is individual bumps instead of a like a round raised blotches if that makes sense and no I haven't taken a antihistimine yet. they remind me of chicken pox kind of and I have had the chicken pox with a positive titer
