cystoceles: do they pull on your tailbone/ si joints and make you feel tired?

Hi,
I have a cystocele grade 1 1/2 or so.... probably close to a 2 sometimes. My questions are:
1. Do cystoceles pull on your tailbone or cause more problems with your si joints?

2. do cystoceles ( or all of the other "celes") make any one more tired?
any relationship there?

anyone one who can shed some light on this or has personal experience would be appreciated.

I had a tvh with anterior and posterior repairs on 8/19/09. Two weeks post-op my tail bone hurt so bad that it thumped. I could not sit well and had a hard time moving around. It came on suddenly and lasted a week, I still feel tenderness in the tailbone area but nothing like I did. I called my doctor during the Labor day weekend to explain my pain and to ask him if this was normal. He really didn't clearly answer my question, just told me to make an appointment. During my surgery he accidently cut my interior anal sphincter and had to repair it also. I was wondering if this caused my tail bone pain. I'm scared it's going to come back full force again. I think the pressure from having a prolasped uterus, cystocele and rectocele would have caused this pain before surgery ---not after surgery and the repairs.
