I'm going to add a picture of my 5 year old Grandson's legs. He gets terrible rashes, then turns to blisters, then pops, leaks and then they turn into open wounds. It happens everywhere on his body not just his legs, this has been happening for a very long time, they checked the fluid in one of the blisters and said there was no bacteria, but, no answers on what this is or what's going on, it's awful !! He is beginning to show large scars all over, they look like cigarette burns, anyone know what's going on? (They are not bug bites)
