I Am Having Pain Above My Pelvis. It Is Severe

I am having pain above my pelvis. It is severe sometimes and goes to my lower back. I have had a complete hysterectomy in 2013. before I had it I was having the same type of pain. I had a cyst the size of a cantelop not malignant. it wasn't too long before the pain returned. it is getting worse and hurts to walk sometime.
