Shingles do not reappear. Herpes does and there are MANY kinds of Herpes & they do NOT have to be connected with sex, only that you had chicken pox. My extremely TOP Dermatologist JUST gave me the latest, sure fire Rx..VALTREX.(new) I used to use Acylovir tabs OR cream but she said "that does NO good". I took 4 Valtrex twice a day and 2, twice a day the next day, and they are GONE! She SAID they would be!
