Your upper abdominal organs normally move a little bit with inspiration and expiration. You may be palpating the edge of your liver beneath the right rib cage. Please inform your doctor about your concerns. He/she can perform a physical exam to rule out enlarged liver and/or hernia. For definitive assessment, consider cross-sectional imaging with CT or MRI.
Hi I have the same symptoms and also when I’ve been bending down ,cleaning,hovering etc I can get a really sharp pain and I have to stay put until the feeling of something catching on my lower right ribs, relieves itself. Quite by chance I had an X-ray fir a chest infection last year and an finding was chilaidities sign . Sounds like you might have something similar ? Hope this leads you to research the symptoms further , good luck
