I am having problem in passing the urine I am not able to create much pressure for the urine and my blood sugar level are normal. I have gone through an ultrasound as well my prostate is also normal. I am in contact with a urologist who after seeing my test has referred me drug alfuzosin -10mg daily for 3 months and that drug is helping me out very well and he suspects a blockage down in the urinal tract. I have no drug habits I am I not married and no sexual contact as well. What could be the reason to this.
