quadrants and regions of abdomen
most practitioners push on the left lower quadrant to see where the patient complains of pain. if pain is felt in the right lower quadrant, then there may be an inflamed organ or piece of tissue in the right lower quadrant. the appendix is generally the prime suspect, although other pathology can also give a "positive" rovsing's sign. if left lower quadrant pressure by the examiner leads only to left-sided pain or pain on both the left and right sides, then there may be some other pathologic etiology. this may include causes relating to the bladder, uterus, ascending (right) colon, fallopian tubes, ovaries, or other structures.
