What Causes Bloating And Lower Abdominal Pain Post Hysterectomy?

HI, I had a complete Hysterectomy about 6 years ago.....I had everything removed. I had a lot of endometriosis, which my Doctor explained he had to remove it even from my bowels, intestines etc I have had great success since my hysterectomy in regards to other female issues cleared up. But, I have noticed that my bloating seems to be more again and my lower abs have a pop & fizz as I called it in the past. Could this mean it is growing back? Also, each year I went in for my annual apt my doctor would tip my Uterus back. Well, I figure since I do not have it anymore I should not have pain. But, I still experience painful intercourse. Is this a ghost pain possibly? Thank you in advance!
