I have been having pain under right rib cage for a year now. Had gallbladder removed 6 months ago. Had no stones but was told it was only functioning at 10 percent. Pain didn't go away. Mostly at night. Can't lay on right side. In early morning I will get lots of twitching sensations if I lay on my back. Only some mild pain during day. I take one Tylenol before bed and one when I get up Pain seemed to start after a 3 foot fall off a ladder. All tests have been normal. Any idea? Thank you, Dona
