[|Human|] Hello, I have white bumps on my penis and scrotum. And i notice at the end of the day, my genital area produces a sour smell. For about a week, one of the bumps swelled up to the size of the marble. It is starting to shrink but it has become the source of a powerful, almost stinging-like itch. Please help
[|AI|]  It seems like you could be having sebaceous cysts in your scrotal and penile skin which is a fairly common complaint in men. One of them might have gotten swollen up or infected to give you problems. The only definitive treatment would be to get a small surgery done to remove them. If they are not bothersome much then you can keep them under observation as they will not give you much trouble. Let me know if I can be of any more help in this regard. Take care. Chat Doctor.
