Hello.
Thanks for posting your query at DoctorSpring.com
I can understand your concern.You seem to be having herpes. It's caused by the hsv virus.
However, it can be confirmed only after your doctor can physically examine you, he can do a tzanck smear if there is a fluid filled blister.
You will need to visit your doctor who can call for the investigation and then accordingly initiate the treatment with valacyclovir. It's important to treat it as soon as possible.Please let me know if you have any queries.
Take care,
Regards.
