Thanks for consulting. I have carefully worked through your case, and I can realize your health worries. Being your physician, I assure you not to worry as I will take care all of your medical concerns. kindly let it examined by an dermatologist near by. or if u can send me the pic of the lesion i can advice you. do not worry it will not be genital herpes as herpis cannot attack multiple site like penis , nipples and arm at the same time until a persons immunity is very low. Hope it helps. If you need further, detailed and quick assistance related to any health issues in future, feel free to ask me a question directly from my profile. Have a wonderful time ahead. Best Regards! Dr. Arunmozhi varman
