To those of you that cathed...did anything like this every happen to you?

I think I am having bladder spasms!! I felt really full and like I needed to pee. I sat on the toilet and nothing, then I straight cathed and nothing!! Yes, I was in my bladder. It was really weird, It felt like my uretha tighten around the catheter and wouldn't let the urine come out. So, I removed it, waited a few minutes, got a new catheter and 300cc of urine came out

I know everyone says it doesn't hurt, and actually doing it doesn't...but after, I feel sore down there and my bladder is tender. Not sure that will make sense to you.

Any help or suggestions are greatly appreciated!!
