Things like this can happen sometimes. It's really a shame that you went through that procedure and all of the pain and it was'nt even the problem.
Have your bladder checked out. It's been a little while since your surgery, you have no infection, so you should not be having pain during urination.
I had three surgery three time concerning this the last one they gave me the full hysterectomy. I laid in bed for two weeks I couldn't eat or use the bathroom. It was the worst thing ever. I told my doc I had a smell coming from my vagina. She called me in. She said it shouldn't be like this plus I was bleeding. So she found that there was infection in two locations. They had to drain plus I went back in the hospital for a week and a half. Antibiotics the works. Don't just let this thing stay in you like that complain ..
I have never had any problems like you have had but here is my two cents. I would get a second opinion to see what is going on or even a third opinion. I would not stop until I had a doctor give me direct answers and was willing to help me. Good luck to you. I hope you are pain free soon.
