My baby has a rash completely covering both legs and feet and partially covering his arms. There does not seem to be any other symptom and it doesn't seem to bother him. Got a slight temperature a couple times but that's it. Had it over a week now. Doctors have done saliva and urine test and all came back negative, they have no clue what it is. They look kind of like little warts if that helps. I have a photo but don't know (if you can) how to upload it.
