In recent months I have had on and off random fluttering by my right rib under my breast. It would happen here and there and be gone. For the last two days has been constant. The last two meals I ve eaten have not digested at all. I burp.many many hours later and some will come up with the burp. I have severe diarrhea now with it and I feel very nauseated. Should I be concerned and go to the hospital? I had my gallbladder removed almost a year ago
