Patient's question:

Itching, scrotum cracked and bleeding with white hard substances like wax on top

Doctor's answer:

The treatment for pubic lice involves removing pubic hair, as well as local cleaning and applying topical creams. Common medications include:
(1) 10% sulfur ointment, applied 2–3 times daily.
(2) 30% stemona tincture, applied 3 times daily.
(3) 1% hexachlorocyclohexane (benzene hexachloride, commonly known as "Jingling") for external use, Jingning cream, and Jidezhi.
(4) Eulifac ointment for external use. These medications are available at pharmacies. Underwear and pajamas must be washed immediately and thoroughly disinfected.
