Hi LizLentellSmith-
I am seeing a pelvic physical therapist and she has said I have multiple "trigger points" in my left and right side of the tendons that connect the abdomen and pelvis--I think I might have endo lesions in these areas and this causes the pain when triggered --but its hard to say for sure. It could also be endo on my intestines or bowel. She has me doing some stretching and massage techniques that seem to help if I do them regularly. If you have an pelvic physical therapist in your area I would highly recommend it--she has been the most understanding and helpful of all my treatement team. Good luck
