What Causes Burning Pain In Lower Abdomen After Vaginal Hysterectomy?

I had a laporscopic assisted vainal hysterectomy 16 months ago. Everything has been going pretty well, except the burning pains in my lower abdomen, sometimes the pain is a shooting pain. honestly, the best way I told my gynecologist who performed the surgery was, it feels like I m having PMS cramps all of the time. She suggested it was possibly because of my lack of sleep, that stomach issues are related to lack of sleep. (which, because of lovely shock of menopause, sleep issues have arisen). I have charted my pains, as per her request, and it doesnt get better with anything except ibuprophen. I do not take ibuprophen all the time, because I don t want my liver to be shot. anyways, my gynocologist has now moved. do I go see another gynocologist? or should I see a regular medical physician? or where should I go from here? The pain is getting worse every week.
