I have chronic pain in my upper right abdomen, like under my rib cage. I was a daily drinker until about a year ago, and I still drink but just not daily....I had to cut back to drinking a few times a week due to heartburn/stomach issues. I've had multiple tests, ultrasounds, a stomach scope, you name it. All came back normal (for the most part, see my next paragraph for details of the only abnormal results I ever had), with no evidence of anything other than chronic heartburn. The heartburn used to be mild, but over the past year it has become unbearable and I now have to take Prilosec or Nexium daily to keep it at a manageable level. Still, you should get it checked out just to make sure.
*At one point my liver enzymes came back as being elevated and they said I had a fatty liver, and that was my sign to change and stop drinking every day. I've had normal liver enzymes ever since then.
