Hello doctor, I ve been having this symptom for about a year now on my penis head. It starts out as a tiny raise and then it spreads. There s no itchy or pain. I took many tests and it seems it s not a STS, not herpes and not fungus. I have been using many creams such as Elomet. The symptom disappeared but they come back in a week or less. I went to see many dermatologists already and now they told me to leave as it s since I don t experience any pain or itchy. I really appreciate any new suggestion. Thanks. Mike
