Hello, Welcome to HCM, With the history provide it is very difficult to make the diagnosis. If you are thinking about the herpes affecting your mouth area. Usually it starts with dryness of the lips, itching which will be followed by eruption of vesicles filled with clear fluid and it is very contagious at the early stages. It never involves the mucosa of the oral cavity and it is obviously seen outside around the mouth. It is a self limiting condition. For few days there will be pain and it will heal by itself the antiviral drugs will not cure the condition but it will inhibits the multiplication of the virus and prevents the complication. Thank you.
