my daughter is 14 years old and has been having large spots come up on her left arm that looks like burns. she says that before the blisters come up her skin feels like someone is holding a torch under it. after the burning eases the blisters start to appear, right nefore your eyes. the blisters will ooze and become painful again. after the skin starts drying it turns into large sores. i dont know what to do, she has already been to 3 emergency rooms and 1 urgent care. so far all the dr's can say is that she is a medical mystery.
