my son is 9 years old, about a month ago he got chicken pox (or that is what the doctor told us - but after more than 2 weeks another doctor told us that it wasn't chicken pox because the bump/rash didn't have water in it). however, about a week ago, new bumps/rash began all over his body even on the palm of the the hand but not scalp, nor inside the ears. he never had fever, and its dry rash. what could this be? we went to 6 doctors so far with no clear answer!
