Hello,
Thanks for posting your query at DoctorSpring.com. I can understand your concern.
These seems to be herpes. However, I cannot appreciate whether there are fluid blisters clustered together or not. Please let me know regarding that.
The treatment would be oral antiviral medication called valacyclovir. You will require a prescription for it.
I would be glad to answer any follow-up queries.
Regards
Dr Kruti
