I have twice had esophageal spasms after starting to consume foods in an Italian restaurant - like tonight. I have had them on other occasions as well typically related to eating or drinking something - one diet coke no ice, one water, twice bread, one a toasted sandwich. Pain is excruciating and lasts up to 15 minutes. Sometimes I will cough up tremendous amounts of mucous. Sips of water or fluid do not end up assisting the spasms. I have lots of allergies. Is there a link between esophageal spasms and allergies and if so are there common allergens?
