Works well. Retrograde ejaculation not a problem (semen backs up into the bladder - so what, it comes out later) This forum taught me that Flomax is the cause of - ringing in my ears (now I'm relieved because I know what it is) - sinuses plugging up My urologist asked me to stop the Flomax and "see how it goes" - I've tried 2 times...each time I get kidney pain on the 3rd day. Taking Flomax again cures the pain. Now I take one every other day. I'd like to stop it, but dribble pee and kidney pain are no fun either - what to do? what to do?
