How to Identify a Herpes Pustule

Herpes simplex virus (HSV) infection cause two different conditions: cold sores (oral herpes) and genital herpes. The symptoms of these conditions are very similar, but the sores are found on different parts of the body; HSV-1 normally causes oral herpes, while HSV-2 generally leads to genital herpes, although both viruses can cause either condition. Individuals can recognize the symptoms of these conditions in themselves, but they should seek out medical advice to confirm a diagnosis in the case of genital herpes.

• 1

  Look for blisters that develop on top of a red rash. In the case of cold sores, these occur generally outside the mouth, on the lips and the surrounding region. In genital herpes, the genitals as well as buttocks, anus and thighs can be affected. According to the Mayo Clinic, these sores eventually break open, releasing a liquid and possibly blood, then form a yellow-colored crust and heal. Once sores have healed, they do not leave scars.

  Be aware of a painful, tingling or burning feeling in the area before the rash and blisters develop. This is called prodrome, and is the initial symptom of herpetic outbreaks, according to the Mayo Clinic.

  Visit your doctor to confirm a genital herpes diagnosis. The Mayo Clinic reports that your doctor can perform blood tests as well as taking samples from active sores in order detect the presence of a herpes simplex virus.
