I have the feeling of a lot of pressure under my right ribs, but I also have pain there too. I was diagnosed with nash 3 and a half years ago. The pressure started about a year ago and they done another liver biopsy. It has progressed to stage 1 liver fibrosis. The pressure is from my liver being enlarged. This may not be your problem, but you may want to have your liver checked to see if it's enlarged. Hope this helps someone.
