I'm having discomfort in upper right abdomen. Not really pain, feels like a foot in my rib cage. Had a gallbladder attack in April. Severe bloating. No gas, no vomiting or nausea, no constipation or diarrhea. Very uncomfortable. I can't sit or lie down. Ultrasound shows no abnormalites. Hida scan scheduled for October. Any ideas of what the issue may be?
