I have these itchy red bumps all over my upper body. it's kind of like a rash now. i have these bumps on my breasts, my stomach and my back/shoulders. what could cause this?

? hives: Can be due to something you ate or a medicine received, also some acute virus infection would cause this, or no reason at all,you can try an OTC antihistamine, unless contraindicated, if no improvement see your doctor

Eval: This can't be diagnosed with the information that is available. A history, physical examination & other studies may be needed to determine cause/causes. Once accurately assessed a treatment plan can be developed.
