I've been experiencing this sharp stabbing pain under my right rib for about a week now. It really hurts when I move, laugh, or take deep breaths. The only thing that somewhat helps is Advil, but the pain is still there, just less intense. I've tried waiting it out, but it doesn't seem to go away, and I can't lay down on either side because it hurts. I'm really not sure what's going on, and I'm a bit worried. Any ideas on what this could be?
