I think one important thing to keep in mind is that MRI's don't always correlate with actual symptoms and what the surgeons find when they go in for surgery. At least that is what some of the PNE surgeons are saying. I have a relative who is an orthpedic surgeon and he told me that they see MRI's that look awful but the patient has no symptoms and then they see patients in extreme pain whose MRI's look normal. So you can't put too much stock in the MRI.
Another question is, do your symptoms correlate with the MRI findings? I read back over your previous post and it says your entrapment appears to be on the right side but you said your deep nerve pain is on the left side. Also remember your pudendal nerve blocks were successful which makes me wonder if there is really much significance to the mention of the possible impingement on the sacral nerve roots. Sometimes radiologists "overread" images and the report sounds worse than it really is. This is what happened with a relative who has cancer and for 6 weeks we worried that it had metastasized to his lungs but it hadn't. We later found out that the radiologist had "overread" the CT scan. Your MRI mentions that the sacral anomaly could have been something that developed, I'm assuming with puberty as you grew, and if that's the case -- why didn't you have pain when you were a teenager? And why were the peripheral pudendal nerve blocks successful? You would think in order to be successful you would have needed sacral nerve root blocks instead of peripheral pudendal nerve blocks but I could be wrong. Just something I would question the physician about. You can ask, if it's the nerve roots that are the problem, why did peripheral nerve blocks help temporarily? Besides, the report is not definite about there being nerve root impingements and I certainly wouldn't go into an type of spinal surgery without something more definite than that.
You also have to factor in your history of heavy exercise including weightlifting that could have caused trauma/injury to the pelvic area. Did the PT you saw evaluate your sacroiliac joints, pelvic alignment, and ligaments? I think it's unfortunate that the PT said she couldn't help but maybe it would be possible to get a second opinion -- maybe from a manual therapist who can evaluate your entire pelvic area and alignment. Check with Peter Dornan on our list of Australian PT's to see if he can recommend someone in your area for a second opinion.
If you aren't able to get any help from PT's then the goal would be to achieve some type of effective pain management until you see Prof. Vancaillie. This may involve some trial and error with trying things like a TENS unit to relax the pelvic floor muscles, pain medications (

I think the internal pelvic exam may also offer some important clues as to what the actual diagnosis is. I'm sure Dr. Vancaillie will be an expert on doing the pelvic exam and determining whether there is pain along the course of the pudendal nerve itself or at the ischial spine which can be suggestive of nerve entrapment. If he concludes you have PNE, then surgery might be the answer. It has definitely given me back my life but it's a long slow recovery so if you can avoid it that would be nice. The good thing is that Prof. Vancaillie is very experienced with treating pelvic pain patients and he has an excellent reputation. He has helped a number of women on this forum.
I know it's really hard to wait for your appointment when you are in pain. Hopefully you can find some temporary pain relief while you are waiting for a diagnosis. Don't be afraid to take opioids if your doctor will prescribe them. I used them successfully for about a year. I did not take he time released forms -- I just took the 4-6 hour tablets and I just took them in the afternoon and evening so I would not develop a tolerance or addiction to them.
I think there is a very good chance you will get better. Please stay hopeful.

PNE since 2002. Started from weightlifting. PNE surgery from Dr. Bautrant, Oct 2004. Pain now is usually a 0 and I can sit for hours on certain chairs. No longer take medication for PNE. Can work full time and do "The Firm" exercise program. 99% cured from PGAD. PNE surgery was right for me but it might not be for you. Do your research.
