I have barrett esophagus for 12 years and now I have had a sore throat for about three weeks. The sore throat comes and goes during the day. I had a egd about 5 years ago?

Need another scope. People with barrett's need to be watched closely with a regularly scheduled scopes at least every two years. Regardless of the sore throat you should get in to be scoped again. Start the the physician that scoped you five years ago.
