I have delt with pelvic pain for as long as the RSD, around 98. I was diagnosed with Interstital Cystitis and spent 3+ years in treatment for it to get it calmed down. I deal with nerve pain from scar tissue. I just got my 4th diagnoses of it Aug. 6th but not one Dr. wants to do surgery due to my intestines being stuck with the scar tissue. The pain is just on the left side also. I also have inside pain which we have calmed down right now so it may be part of RSD.

Anyway to make a long story short, I would find a good Urologist. They can check you out and do lidocaine treatments to help calm down things going on. Also I use a lidocaine patch at times and I also sleep with a heating pad on my left hip area. It sure doesn't seem to want to go away.

Feel better soon.
