Given the data you provided, it seems likely that you might be experiencing problems with the swallowing reflex. Swallowing is a complex process in which several muscles in the mouth and palate simultaneously work together in order to enable passage of the food from the oral cavity into the esophagus without returning it back to the nasal cavity. This condition might be due to the inflammation of the surrounding tissue, but a check up with an Ear, Nose and Throat specialist for a physical exam is still recommended.
