I have a rash that developed back in the end of april beginning or may and it is bad. There are ulcers or blister not sure which on my face, back, arms, legs, and my butt. It showed up real red and swollen looking like there was something in them. When I took my shower and ran my bar of soap down my legs it pulled little like rocks out of the blisters the soap looked like a porcupine. I need advice please ASAP!!!!
