SHINGLES

So I need someone to calm my anxiety please. I went to the hospital today for a rash and found out it is shingles. Unfortunately the hospital was not helpful and didn't answer my questions about if it will effect the baby. They said to talk to my OB and prescribed me Tylenol with codeine???? I can't see my OB until tomorrow because he is delivering a baby today. Has anyone had shingles while pregnant?? Will it effect my son at all???
