 [ Symptoms ] my 3 yr old has been diagnosed with shingles he has never been exposed to chickenpox and has been vaccinated how is this possible sores started on the back of his neck itchy then started down the left side of his back also one on the right shoulderblade and on the the left side of his face near the ear there is no red rash or fluid  filled blisters just scabby itchy sores [ Disease ] i can not comment on the accuracy of his diagnosis since i can not examine your child but a three year old who has been vaccinated with the chicken pox vaccine can certainly get painful shingles it does not happen very often but i do see this several times a year in my busy clinical practice
