I slipped going down stairs and fell on my back and slid down a few steps. I have pain on the right side just below rib cage and pain on my back right on my ribs. I m 38, 5 9 , 145 lbs and no other health issues. I have no trouble breathing, but it hurts when I cough, laugh or twist, bend to the side. There are no bruises, but the area is tender and hurts when I apply pressure. Other than fracturing a rib or two what other damage should I be worried about?
