I am having problem in the upper back portion at about the diaphragm position .i feel sensation and irritation in this area since last one year. Sometimes it feels in the backward side while swallowing food also. I am suffering from acidity and gastric problem since last 8 years. I underwent endoscopy for this in January 2017 but nothing was detected. Doctor prescribed me Sompraz L for a month. For some period the problem subsided but then started reoccurring. I do not want to undergo endoscopy again. Please suggest.
