Possible reflux: You may be beginning gastritis, reflux or ulcers. See a physician to get instructions regarding lifestyle changes, medications, and possibly endoscopy for the proper diagnosis if this has been going on for a while.sometimes esophageal spasm can set this off as well and getting an exam with a full history will help you.
