What Causes Pain In Upper Abdomen Along With Vomiting Post Cholecystectomy?

II had my gallbladder taken out over a year ago and still having a bad pain under my ribs and throwing up. This seems to happen about every 3 to 6 weeks. Been to ER several times and had blood work done and all comes back ok. Upper hi and lower go came back ok. I have a dry cough that comes mostly at night and belching a lot. I thought this was a free site?
