For two weeks now I have had a pain on my left side behind my upper rib cage. It hurts more towards the back. I haven't been sick, I woke up and was hurting and thought it may have been how I slept that night. I've put icy hot patches on it and it doesn't seem to help. Tylenol will take the edge off of it but really doesn't work. When I move in certain ways a sharp pain will shoot through that area and take my breath away. When I take very deep breaths, it hurts really bad.
