What does it mean if an upper GI indicates "a slight decrease in size of the vallecula on the left side compared to the right. Possible small filling defect along the posterolateral wall of the vallecula on the left is not entirely excluded" I was sent for the upper GI from my family physician. I have had discomfort on the left side of my throat when swallowing for about 7 months. The ENT went through my nose with a camera twice and saw nothing. I also had a scope of the stomach and the gastrontologist indicated a few ulcers looking up to the vocal chords, some stomach inflamation but nothing else. They doubled my dose of nexium since they both thought the ulcers were due to reflux. The upper GI didn't indicate reflux. In just the past several weeks, the left side of my throat pops or clicks when I swallow. There is also some pressure on the left side since the popping started. If I turn my head all the way to the left and swallow, it doesn't pop. If I turn to the right, it pops every time. Otherwise it pops about 25-50% of the day when swallowing with my head straight.
