Hi, age 53, I have enlarged prostrate, 30gm and post void urine 85 ml. Urine flow weak and feeling constant need to urinate. Psa 0.5. Prescribed veltam plus by doctor. Taking med for over a month. Improved flow of urine after a week but now condition kind of fluctuates. Better for few days and then again urine flow goes down and feeling returns. Do I need to change meds or go for surgery to get a stable urine flow.
