Swallowing Difficulty

Acid reflux (gastroesophageal reflux) is still a very likely cause of your symptoms, even though you have not had noticeable heartburn or other classic symptoms of acid reflux.

Another explanation for your swallowing difficulty could include a narrowing that is called an esophageal ring. Esophageal rings can occur without a clear reason. Sometimes they are associated with allergic inflammation in the esophagus called eosinophilic esophagitis, which might be related to food allergy.
