I had surgery about 10 months ago, I have not lost any weight and now I am having pain in my left upper back, also I am belching a whole lot. And have to throw up to get relief sometimes. I can't go back to the doctor that did the surgery right now, because I no longer have insurance. Is anyone having this problem, or have any idea why this could be happening.
