Yesterday I had an Upper GI endoscopy. Afterwards, swallowing was very painful to point that the Dr recommended a visit to the ER to check for a possible esophagus tear. I did not have a tear but they termed it abrasions from the endoscopy in my throat. Today, it is less painful but still hard to eat - so I m mostly drinking fluids. The front part of my throat where the thyroid lies is very sore. Can the endoscopy cause bruising or swelling to this area (thyroid or cricoid cartilage) which is causing the pain when I swallow - especially since the esophagus is at the back of the throat?
