A 19-year-old male asked:

I have herpes zoster, the doctor gave me the antiviral, and other medicines, what are the signs of the blisters and the rashes are getting better?

A week to 10 days: The rash should be completely dry in 7 to 10 days. If persists or new vessicles appear then it would be concerning. Sometimes they can start looking worse before they better.
