What can I do about shingles, herpes, or ringworm on the testicles and penis?
Herpes or shingles in the genital area needs antiviral tablets like acyclovir or valacyclovir, started early, and you should avoid sexual contact until the sores heal. If it is ringworm, use an antifungal cream such as clotrimazole or terbinafine, and keep the area clean and dry. If the rash is painful, spreading, or unclear, consult a doctor for proper confirmation and treatment.
