My urination flow starts a normal then after about 3 seconds it stops and I have to concentrate about 5 seconds before it will start again and finadish. The feeling when it stops is like that feeling that you have to go really bad but are holding it back until you get to a bathroom. When it stops it is involuntary. It just feels like it pinches off inside and stops flow. What could cause this? I do take staterra which when I first started this med it did cause urination flow to be weak and difficult during the entire process of emptying. But after a few weeks that symptom went away and I have had no problem as such for one year. Could the side effect reappear with straterra and present itself a bit differently as I described above?
