I had my gallbladder removed 25 years ago.About a year later ,I began to notice a fluttering feeling under my HUGE scar under my right rib cage. For years ,I would press gently,and it would stop. Now,it was getting harder to make it stop and the fluttering got worse. Last week,as I was trying to make it go away,I felt it get stuck under my ribs. Going to the hospital in the morning. I will post the findings soon as I can
