I have had a constant, lingering pain for over a year now in the VERY lower right side of my abdomen/pelvis. It's almost like a hollow feeling, just constantly nagging me. Sometimes my intestines will be very rigid and the hollow feeling seems to intensify...other than that its just a constant lingering pain in the same spot. I have had ovarian cysts previously, but recent US all show clear. Any ideas, or thoughts could help!
