Do you have any suggestions for natural help with achalasia?

Achalasia can be bad: Achalasia is defined by absent peristalsis in the esophagus & incomplete relaxation of the lower esophageal sphincter (les). It may be a "primary" esophageal motility disorder, or "secondary" to cancers invading the les (pseudoachalasia), chagas disease from reduviid bug bites, amyloidosis, sarcoidosis, eosinophilic infiltration. This is not something you should ignore or that fixes with herbs.

Adjunct only: Achalasia is life-threatening short-term. If you've been offered definitive treatment, take it. Don't waste time or focus on herbal / pop / health-food-store alternatives. If you have an evidence-based holist in your area, you may get some recommendations for discomfort after treatment.
