What a day.
Apollo weathered the upper GI and swallow study like a champ. They had a wonderful view and saw, clear as day, the indent in his esophagus. Yup, they found his feeding issue.
The unbelievable part is, they think the indent may be caused by another vessel compressing his esophagus. The cardiologists have been called in to look at the images taken today. Waiting to hear from them.
