Hi. Thanks for posting your concern at HCM Minor traumatic wound on penis would heal on its own. You can apply a topical mupirocin ointment to prevent secondary bacterial infection. However as you mentioned, in the past you had applied Herperax ointment(as prescribed by your doctor) which contains Acyclovir(an antiviral) and also since it has recurred again in the same place, it suggests a possibility herpes to me. Since i don t have the opportunity to examine the lesion, therefore, I would advice that you visit a dermatologist for a physical examination of the ares of concern. Your dermatologist might ask you about your sexual history and also might ask you to get a few tests if he/she suspects it to be herpes. take care regards
