Fatty Liver :: Feeling Of Swelling, Bloating And Pain In The Upper Right Abdomen

Last week I went to the hospital because my stools were black. They tested for blood but found none. Blood tests showed slightly elevated liver enzymes so they did an US and diagnosed me with fatty liver. That evening I began to notice swelling/faint pain in my upper right abdomen. I thought it was because of all the pressure from the US. It's been a week and it seems it's only gotten worse. Pain/swelling feeling extends from below the rib cage, don't my right side and i also get intermittent pain in my right lower back.

Once I got the diagnosis I changed my diet and stopped drinking. I'll be honest I used to eat horribly. Fast food, frozen meals, high fat, sodium and sugar. I became almost addicted to minute maid lemonade and drank 1-2 liters a day. All that HFCS is what I think mostly contributed to the fatty liver. I don't drink all that often (although when I did it was usually heavy). 2 years ago I used to drink a lot (though still only on the weekends) but up until my diagnosis it would be maybe few times a month tops.

I'm beginning to worry that they misdiagnosed fatty liver and it's something more sinister like cirrhosis. Other symptoms include fatigue, sometimes when I breathe I can take a full breath but it's like I'm not getting enough oxygen. It's hard to describe, almost as if the swelling in my abdomen is crowding my lungs. Lastly, my stools are now very light brown and loose (I honestly can't remember the last time I had a normal BM). I have a follow up with a GI Dr but that's not for 3 weeks.  All of this has triggered some severe health anxiety that I once had as a child after an oral surgery.

Does anyone with fatty liver experience this feeling of swelling, abdominal bloating and pain in the upper right abdomen, right side and lower right back?
