Since having been recently diagnosed with a fatty liver also, I totally understand what you are going through. I feel pain under my right breast at all times and sometimes in my upper back. Your GI will probably do a CAT-scan or an MRI. IF I were you, if at all possible, I would go for the MRI, because I had a CAT-scan and they still had me go for an MRI.This is all normal for a fatty liver, so don't worry{I know that is easier said than done}. I had never heard of a fatty liver, so I have done tons of research on this. This web site has helped a lot too. There aren't many treatments for a fatty liver, but from the advice I have gotten is to go on a very low fat diet and take Milk Thistle and Lecithin.Also some people feel pain and some don't. They may decide to do a liver biopsy too. Don't let the word "biopsy" scare you. That is a good thing to have done. It can tell them how much damage has been done to your liver.Good luck !!
