Herpetic lesion are painful fluid-filled lesions that can be found anywhere on the skin or external mucous membrane of humans. These lesions are caused by the Herpes Simplex One virus or the Herpes Simplex Two virus. Oral herpes is more often caused by Herpes Simplex One virus.
Herpetic lesions occur after initial infection after which the virus lays dormant in nerve cells. The virus may be reactivated periodically, causing herpetic lesions.
Oral herpetic lesions are also known as cold sores. They usually manifest themselves as painful fluid-filled lesions in or around the mouth and tongue. Pain usually proceeds the lesion by one or two days. If the lesions are not filled with fluid or painful they are most likely canker sores.
The appearance of herpetic lesions on the tongue are usually proceeded by tingling in the area of the lesion. Reactivation of the herpes virus can be caused by illness, stress or menstruation.
