Patient's question:
A blister has appeared on the penis for 3 days. It feels a bit hot and itchy today. What could be the cause? Is it serious?Doctor's answer:
Suspected balanitis. It may be caused by neglecting hygiene, unsafe sex, or frequent sexual activity. It is recommended that you clean with salt water before bed every day, appropriately reduce inflammation to prevent infection. Additionally, apply erythromycin ointment after cleaning. Wear clean and breathable underwear, and make sure the crotch is not too tight to avoid rubbing the bumps and causing bacterial infection while walking. Additionally, you can take roxithromycin orally.
