Ya me too. I think it's from the insertion of the urine catheter. I too had pain when urinating. I had to pee bit by bit to lessen the pain. Frequency also increased but not much urine every time. Just got the urge. It only went away after 3 weeks in my case. Think the insertion somehow tramatised the wall of our ureters thus causing the pain. 2.5months now... I can still remember the pain. yikes!
