herpes zoster can definitely come back but i am concerned about the accuracy of your diagnosis so i would strongly suggest that you see a dermatologist for an expert second opinion before just taking the medications again.
can shingles flare back up once you finish antiviral medications. i was diagnosed with shingles on my scalp on sept. 27 2015. i was prescribed famciclovir 500 mg 3x daily. i just finished the medication on oct. 2 2015 and i have noticed that there seems to be new areas on my scalp that are beginning to itch and new blisters when scratched - brings me out of my skin so to speak. could another dose of famciclovir be helpful? or needed.
