I Had A Hysterectomy And Rectocele Repair 12-23-15. About 6

I had a hysterectomy and rectocele repair 12-23-15. about 6 weeks post op I started having left side pain. I had an U/S to see if there was an ovarian cyst which was negative. I have terrible pain the size of the hand from my left ovary to the bottom of my ribs then across my abdomen. Had xray= normal except Phleboliths found. What other testing should be done or what type of doctor should I see.
