Dear Sir, Greetings of the day Myself is S S Ahmad. My age is 47 now and I have a problem of urine dripping [few drops] even after 10 to 15 minutes after passing the urine to its full extend. I am facing this problem since last 15 years. I told this problem to some doctors in the begining and I still remember that at that time one doctor advise me ultrasound and the radiologist who conducted ultrasound told me that about 20% urine remained to be discharge in the bladder but at that time the doctor told me that is normal and prescribed no medicine and no dietary or life style changes. Now recently I read some literature on this topic and came to know that it may be an indication of some problem in prostate gland. So I consulted the urologist and after going through the ultrasound and other tests the doctor has advised me table flotral 10 for three months. So I request you sir to kindly advise me what kind of dietary and life style changes are now required for me. Weather this problem will be solved permanently or not. I am worried kindly help me. Thanks S S Ahmad
