my daughter is 6 yrs old and has 2 spots that have a group of tiny blisters.....the blisters on her thigh have mostly poped and scabed but there still are a few there and the other group is on the outter side of her foot...none of them have poped and they itch and burn...I have put desitine on them to try to make it soothing and giving her benadryl but now im at a lost and the bunch on her thigh looks like a red patch is starting around it...help please if you can
