Last Monday I was eating some chicken and rice soup and when I swallow a bite my esophagus felt like it was burning like when you put something too hot in your mouth and it scalds the upper palate. Afterward for a couple of days it burned when I drank coffee and the esophagus was uncomfortable when swallowing. After a couple of days I called my gastroenterologist to get an appointment but he has nothing available till 12/6. I made an appointment with his NP tomorrow. I now have stomach pain (mild) and I noticed about the last four days my stool is darker than usual. I am wondering if there was something in the soup that could I swallowed that made the sensation of burning when it was actually scratching the esophagus.
