I have had problems too - but the opposite. I need to pee ALL the time since the injury. I thought there was an infection but tests came back negative. Also, I'm not in control as I was... it's actually becoming an issue because I can't seem to go 20 minutes without the desperate urge to pee and I end up not doing certain things because of it. I don't know if it's because the injury or not, but I know I didn't have this problem before.
