There is no difference between herpes-like mouth sores and herpes stomatitis, they are the same disease, oral herpes simplex. Oral herpes simplex is a skin and mucous membrane disease caused by herpes simplex virus infection, which may be triggered by fever, cold, ultraviolet light, and mood changes. It is characterized by localized clusters of small blisters, and during the incubation period, patients may experience fever, headache, fatigue, and muscle pain. For patients with oral herpes simplex, systemic antiviral therapy is the mainstay, and antiviral drugs such as acyclovir and valacyclovir can be taken as prescribed by the doctor. During this period, medications such as acyclovir ointment and penciclovir cream can be applied locally to promote recovery. In case of recurrent herpes labialis, laser treatment can be taken. If you suffer from oral herpes simplex, you should go to a local regular hospital for a relevant examination and cooperate with the doctor for standardized treatment.
