Herpes simplex infection of the lower back and buttocks—also called sacral herpes simplex or genital herpes—is a common recurrent skin condition associated with infection by the herpes simplex virus HSV. HSV infection usually appears as small blisters or sores around the mouth, nose, genitals, buttocks, and lower back, though infections can develop almost anywhere on the skin. Furthermore, these tender sores may come back periodically in the same sites. Infections with the herpes simplex virus are very contagious and are spread by direct contact with the skin lesions.
