I've been having really bad heart burn on and off lately. The ENT did see some redness around the bottom of my esophagus when he looked with a scope. He gave me zantac but then I developed what feels like pressure in the middle of my chest/lower throat. So I stopped taking it after 3 days. I'm going to the GI doc soon but can anyone tell me if they've experienced this? The pressure in my chest and throat has me really freaked out and scared.
