I was having upper abdominal pain for quite a while, after ruling out an ulcer I wound up having my gallbladder removed in January and the pain went away. Now I'm having new problems. For the past month or so, a few times a week, when I wake up in the morning I feel horribly sick. I have upper abdominal pain, kind of burning, grinding, hard to describe, nausea, go between sweating and the chills, and have several bowel movements. The more bowel movements I have the better I seem to feel. This usually goes on for at least half the day before I feel any better and still leaves me with upper stomach pain. I'm also feeling a little short of breath. Right before my gallbladder surgery I had a complete cardiac workup, ekg, echocardiogram, stress test and everything was fine so I'm pretty sure it's not heart related but don't know what this could be. I know I need to have an upper endoscopy done but I'm dreading it and putting it off. Does this sound like gastritis or IBS?
