I would urge you all to read the following article if you have herniated disc, sciatica, pins and needles, pelvic , buttock, hip thigh, quad pain. As an endometriosis sufferer I have had these concerns and am currently awaiting another lap in March to see if I have adhesions or more endo returned post hysterectomy 2003. It has been the same pain i have had through three other operations plus the hysterectomy due to adenomyosis, and got relief each time when my pelvic issues were erradicated. I show bulging discs on MRI one touching a nerve. But my pain is mostly on the right and these are on the left. I kknow about referred pain but I also know it can be caused by cysts inthe pouch of douglas as you will read in this article, and I have have them every laporscopic surgery too.
