Tummy troubles all of a sudden

I have had uncomfortable swallowing (as if something is stuck), a feeling of having food stuck and just sitting in my intestines, my stomach growls when I swallow, and when I go to the bathroom, my stool is very thin and yellowish, for almost a month now.

I feel like I need to burp and go to the bathroom, but I can't. Really uncomfortable. Have tried modifying and decreasing amount of foods eaten, but nothing seems to help. Sometimes I eat, and it feels better. Sometimes I eat, and it feels worse. Getting frustrated. Had an endoscopy.

Doctor found inflammation and polyp in esophagus. Normal stomach. Results came back that I have h. Pylori. Are these symptoms normal?

I feel like there is something more going on. Have had blood tests and liver enzyme checks. All have come back normal. Am on Dexalant. Doesn't seem to be doing much.

I am 33, thin and in shape with a relatively decent diet. Not sure where to turn, but feeling not so good and getting worried. Antonella have any tips, suggestions or similar story?
