I have a pain about 5 to 6 inches below my rib cage and the pain travels upward what could this be?

You see it makes me sick, I can't bend down or move or even put to much pressure on my stomach it really hurts. At times I feel like throwing up and at times I do. I started thinking that it could be my appendix and now I'm thinking my gall bladder. Anyone have any advice please help!!!
