My daughters and grandchildren seem to be passing something back and forth. We get itching, biting, and a fluttery feeling all over. Some of t6hem have small spots, barely seen. We ve been to a lot6 of doctors, dermitologists,, etc. they say we have nothing wrong with us. This has been going on for months now, and we are going crazy because no one believes us. What could it be? The baby is sc5ratching his head and neck like crazy.
