question: My mother is 82, she has developed tiny bloody blisters that form and break open along the shin of her leg. They DON T ITCH or BURN. She has had other skin eruptions in the past, that have pus and itch and burn. These are totally different. Her immune system is compromised. She has acute leukemia. She has seen a dermatologist for her other skin problems. She has a cream for the other skin condition.
