Have you been doing kegels? If not, you need to be doing these everyday. It can take a year before the muscles are strong enough. It's been more than a year since my surgery and I notice that I still need to be doing my kegels in order to get stronger. Kegels are a long process. You should definitely see you CR dr. also.
No I haven't had that surgery but do know you'll need to build your muscles there again. It wouldnt hurt to give the nurse a call to see if they have any suggestions.
