Hello,
Thanks for posting your query at DoctorSpring.com. I can understand your concern.
The lesions are of herpes zoster or shingles.
It presents on one side , can extend from front to back, it's called dermatome. Both the lesions have a group of fluid filled blisters.
The treatment for it would be to take valacyclovir, which would require a prescription.
Application of neosporin cream over the lesions will be helpful.
Please let me know if you have any follow-up queries.
Take care
