I am trying to find out what organs are under the right side of the rib cage. I had surgery on the 17th of this month, shortly after that (approx. 36 hrs) II had difficulty breathing and pain on the right side of my rib cage. I went to the E.R. they ran test said I had tested positive for a dime something enzyme, but diagnosed air under rib cage and sent me home,the doctor said I would feel better in two days, well, I still hurt when I breath and it is coming from the right side and my rib cage still aches.
