Herpes on the waist is considered to be herpes zoster, which is a varicella-zoster virus infectious skin disease that initially presents as erythema and blisters distributed unilaterally along the nerves and can be accompanied by pain. The pain varies from person to person; some people start with no pain and begin to experience it later. Some tonic shingles have only simple pain without a rash, so the presentation of the shingles rash varies from person to person. In the later stages, the blisters can dry up and crust over. Oral antiviral therapy with valacyclovir hydrochloride is recommended, but it should only be taken if the liver and kidney functions are normal.
