Hi I developed the rash last Saturday no not until sunday night,had prior symotms about a week before. Went to drs tues and was prescribed the famciclovir for 7 days. Mine are basically on forehead and close to hairline. At this point I have had no oozing only itiching,headache,eyes feel a little different, Should I go back to drs for another script and does it sound like I might of caught it in time that it will heal quicker?
