My urologist said my thrombosed penis vein is ok since it causes no pain or erection problems. he didn't see it....i described it to him. is he right?

Yes: A thrombosed penile vein or lymphatic vessel is almost always self-limiting, benign, and not usually recurrent. Most often related to excessive or prolonged friction related to masturbation or sexual activity. Usually, the thrombosed vessel softens and diminishes with time, but may persist on occasion. No treatment needed unless residual prominent vein is psychologically bothersome.
