The answer is #3 Diffuse esophageal spasm.
Here is another radiograph that shows barium contrast material that highlights the esophagus in a spiral formation. The esophagus is made of smooth muscle and it contracts to propel food down to the stomach. Esophageal spasm is an abnormal uncoordinated contraction and it can cause mid chest pain and slow the progression of food after swallowing.
Signs and symptoms of esophageal spasms include:
- Pain in your chest, often intense, which you might mistake for heart pain (angina)
- Difficulty swallowing (dysphagia)
- The feeling that an object is stuck in your throat (globus)
- Bringing food back up (regurgitation)
- Heartburn, a burning sensation that may radiate from your upper abdomen to your neck, sometimes leaving a sour taste in your mouth
