Hi, I have small blisters that seem to come out of know where they just appear and at first they are flesh colored.. But when I try to open them it seems like just blood comes out and then they turn bright red for days. any Idea what this may be? I am 30 yrs old 160 lbs and 5'5. I do have a somewhat weakend immune system since i have a history of Kidney/bladder problems and im on a few meds but all this bump stuff just started. I do have hot flashes alot due to an early historectomy so Im hot all the time and constantly sweating! Could that be relevant? I don't know. Any help/advice you could give me would be greatly appreciated! Thank you!
