### Patient: Doctor, I have been experiencing trouble swallowing food and my chest feels tight.
### Doctor: You might have a stricture of the esophagus. We'll need to run some tests to confirm. We'll need to start with a complete blood count (CBC) and intravenous fluid replacement. Then, we'll have to perform an upper gastrointestinal endoscopy with biopsy, plain x-ray, and esophageal dilatation. Additionally, we'll need to do an electrocardiogram and biopsy.
