Yes--request your records...go see another doctor...
I don't think your body failed you--the epi helped you relax and helped you dialate...up to that point, it was on track...
I'm guessing they told you when to push since you couldn't feel it and I'm thinking you may have pushed against a cervix with a lip or something and may have caused it to swell--any pushing after that would've only increased the problem. Then I'm also guessing you were flat on your back or at a slight incline making pushing more ineffective than if you could've squatted etc.
I'm no Dr or anything--but it would've been nice if INSTEAD of pit, they had turned your epi down low...then see if you could FEEL enough to stand and squat--or at least elevate a bit...then maybe you could've had more effective pushing. A c/s was the LAST resort--if baby was doing fine and you were too (except for being tired etc) it would've been better to let you rest...and see where your labor went--turn off the pit and see if you could've let your uterus and muscles rest and then try again ya know?
I pushed for 3 hrs--on my back... I was very close to a c/s also--and I'm annoyed that it got to that point.
As for your bladder/urethra/incontinence--It could just be the swelling/healing...but I'd get a 2nd opinion...
Please don't cry over peeing all over yourself. Our bodies are wonderful, but birth is a very hard effort--and all of our systems get involved...your body is a wonderful machine and it can heal and be well again! The one thing I would remind you is go and get some probiotics--acidolpholus, plain yogart, etc. The antiboitics can really make a bad situation worse with a yeast infection (either vaginal or thrush if you are breastfeeding!)
Mama--remember this--in all things like this that are SO DIFFICULT, we learn. We learn and we empower ourselves--and we can in turn become a teacher for others. I had a BAD time after my dd's birth and nursing was a BITCH! BUT, because of my experience, I know I have made a difference in many people's lives with my convictions with breastfeeding and birth. YOU can also be convicted and help others!!! But for now, rest, heal, and relax.
Your body made a miracle...then you worked your hardest (even against some tough obsticles--the medical community!!) to get this baby out...and in the end you produced a healthy and happy baby. Your body DID NOT fail--your attendants might have failed you though--and that is why I think you need a 2nd opinion!
I'm thinking of you and sending you healing vibes!
