I feel like I have to urinate badly, but then when I go, there isn t much urine. I feel like my bladder is completely full, and I m about to burst. The last time I felt like this I ended up with kidney stones. I don t have any pain in the back, but do feel almost like someone is pushing on my bladder, then it eases, then it feels like someone is pushing on my bladder again. Almost a pulsating feeling like its being squeezed, let go, then squeezed again. Maybe a bladder infection?
