Hello, Oral herpes is the viral infection which occurs due to many reasons like having intimate or personal contact with someone who infected or touches open herpes sore or something that has been in contact with the herpes virus, such as infected razors, towels, dishes, and other shared items. After the first infection, the virus becomes dormant in the nerve tissues in the face. Sometimes, the virus later reactivates, causing neuralgia like condition. I would suggest you to oral pathologist as well as a neurologist for proper treatment. The doctor may order a viral culture test, viral DNA test, and Tzanck test to confirm the diagnosis. The doctor may prescribe antiviral drugs like Acyclovir, Famciclovir, or Valacyclovir at least for two weeks along with anti-inflammatory drugs to treat the nerve condition. Sometimes the doctor also prescribes anticonvulsant drugs. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Harry Maheshwari
