Hi everyone, I have been suffering from this burnign sensation in my esophagus since July 2nd of this year, i have a gnawing pain in my upper abdomen, sometimes I feel a mild prickling pain my my left upper quadrant and sometimes on the right upper quadrant, I have mid upper back burning sensation and mild pain with the burning sensation in my esophagus, I sometimes get nauseated and a few times have had very loose stools, no vomiting and no bloody stools. I also feel mild esophageal spasms, very few. I am terrified it may be something worse than acid reflux, like cancer. Anyone else have same symptoms and what were you diagnosed with? I would appreciate input, I have an endoscopy next tuesday, so scared.:dizzy:
