It's been 5 days I have this pain/presure on my upper abdomen that goes through my upper back. It feels as if something is stuck in the middle of my chest and at times it moves making harder to breath. It doesn't go away, but at times gets worse, especially at nights. When I ice-skate which I enjoy, I don't feel it. I don't know why, because I excersice, or because it's enjoyable and I don't notice it... I have my gall bladder removed 5 years ago because of gall stones. What can cause this??? I was at a doctor's office and still haven't been able to go for any tests because of burocratic nature of our healthcare system. Please help me understand what this could be, if you can.
