I had surgery in December 2015 and they abalated endo from "left side" (your guess is as good as mine). Fast forward a few months and I'm regularly getting low pelvic cramping and pain in my rectum before having a BM. I'm not constipated, nor do I have diarrhoea. I also have pain in my rectum when I pass gas. I'm wondering if these are endo symptoms or IBS symptoms... Any help/advice welcome.
