Did you take meds during that three months? When I had my first endoscopy my esophagus was red and irritated (but not Barrett’s). Since then, I’ve been on protonix which heals the esophagus and the esophagus is pink and healthy looking even though I still get reflux at times. After your last test, did they suggest you have another endoscopy in the future to monitor? If concerned, maybe it’s best to just make another appointment rather than worry. Better safe than sorry, right? Every time I have a colonoscopy, I request an upper endoscopy as well since I’ve had ongoing issues with reflux, take meds for it and my brother died at 59 from esophageal cancer. He had silent reflux w/Barrett’s and never knew he had an issue until it was too late. I always worry about genetics since I have other identified genetic mutations. I hope you get some answers and they are all good news.
