Neasea and fullness can be indicative of GERD.
Other possibilities can be a mass, ulcer, esophageal dysmotility, or gastroparesis.
An upper endoscopy would be a more comprehensive test. More specialized testing, including the 24-hr pH study +/- esophageal motility studies, or a gastric emptyingn scan, can all be considered.
I would consider a gastroenterology evaluation.
Followup with your personal physician is essential.
