Thanks for the query.
There is a possibility that you have developed herpes
The treatment given to you is antiviral
The lesions should have healed by now.
There might have been a secondary bacterial infection.
You may need treatment with antibacterials.
A photograph would have helped me much better.
Please meet a dermatologist
for exact diagnosis.
