Hi everyone, im not sure what this rash is on my 6 year old son, we saw 3 different doctors all with different answers. Furst said mosquito bites, then another one said bed bug bites ( no one else has this rash and i flipped my house upside didnt find anything), and the other doctor said a bacteria from hot tub( we went in a day before rash started, and our condo management mentioned after that the water was not filtering properly. To me it looks like shingles, he was vaccinated against chicken pox at 15 months so is shingles even possible?
