My sister developed a rash a month ago. It has spread over her entire body, except her face. Red dots, raised bumps. Red dots. They never itched. They are painful and are all over her back, under her arms, butocks, arms & legs. It statred to go away and now it is back and much worse! What could it be? Shes had shingles before and this isn t the same. She has red dots everywhere! I looked at chicken pox photos, but those dots are much bigger but simular. Help us please. Shoud she go to the ER?
