N.S.
My daughter got this when she was 11 months old (she is now 15 months). She had all of the classic symptoms, fever, did not want to eat, sores in the throat. It ran its course in about 5 days. She did not have any vomiting associated with the herpangina.
I do not know what the other symptoms are or if vomiting is normal or not. I am sorry that I am not more help. The only thing that I do know was that there was no medicine for it as it is a virus. I just tried to make sure that she stayed hydrated.
