Hello, Thank you for posting on HCM. The condition you described is difficult to diagnose without proper clinical examination. From your description, i would suggest the diagnosis of Herpes labialis. Its a common viral infection associated with fever followed by blisters in and around mouth. It is notorious for being recurrent but nothing serious. As of now consult your nearby dermatologist who would prescribe you oral antiviral drugs( Acyclovir/valacyclovir) and creams for local application ( Antibiotics with or without acyclovir cream).A few days on the meds will resolve your condition. Hope this will solve your all queries and wish you best of health. Thank you Dr Hardik Pitroda
