What causes esophageal spasms?

The precise cause of esophageal spasms is unknown. Some in the medical community believe the problem results from faulty nerves that are responsible for how the esophagus muscles work. Too much acid in the esophagus could also lead to the problem. Excess acid can be due to having heartburn for a long time.

Some people notice esophageal spasm symptoms after eating hot or very cold food or drink. But spasms can happen anytime, even when you’re not eating or drinking.
