What causes esophageal spasms and what is the treatment for this?

Chest PAIN from DES: Des is a motility disorder of esophageal function. The muscles of the esophagus forcibly tighten, typically unpredictably, resulting in severe chest pain. Distinguish this from situational esophageal spasm, "nutcracker esophagus", and of course non-esophageal causes of chest pain. Speak with your gastroenterologist about rx options to minimize attacks, where to go, what to take when pain develops.
