Herpes zoster?: If the pimples/rash on your back and "rib cage" (your chest?) are all in one large cluster, you probably have herpes zositer, also called shingles. It's caused by a different herpes-type virus than the one that causes oral herpes (cold sores). Shingles needs immediate diagnosis and treatment to avoid serious pain both in the next few days and ongoing pain later. See a doctor ASAP.
