Pressure under right rib? Hernia?

Hi! On Thanksgiving I overindulged (but not anything crazy) but noticed I felt much fuller than normal. After dinner my family took a long walk and then headed back to the hotel. While I was waiting for the hotel elevator I felt a weird feeling sort of my left lower rib area, that went away pretty fast. It didn’t hurt, but was enough to get my attention. Later that evening, after playing games with my family, I went to bed. When I laid down I felt SUPER full again and my heart was embracing. (133 BPM). The next day I felt pretty much okay, just not hungry. Since then, I have had an on/off dull pain under my right rib that feels like a bubble. Today, the pain is just persistent but still very dull and I feel it mostly when I sit. I have been to the doc and she said she didn’t feel anything to be concerned about and it didn’t hurt when she was poking around. Labs all ok. Does this sound like a hiatal hernia? Gallbladder? Something else entirely? TYIA!
