I am having an endoscopy on Tuesday along with a colonoscopy. Never had either done before. If you have a polyp in the esophagus is it painful? I have had discomfort in the upper part of the esoph. and when I take a deep breath I feel discomfort and sometimes pain on the right side of my neck next to my throat where my gland is. Nothing is swollen. I have had this sensation for several months, right before I had my gallbladder out and pretty much since the surgery. I am taking Nexium to see if that would correct the problem and it seemed to subside after 2 weeks but now it is back again. Seems like the Nexium isn't doing the job after all. Does any of this sound familiar with reflux? I am so scared that it is something worse.
