Hi. I'm having some issues with swallowing and I have a history of one esophageal stricture and GERD. I had an Barium Swallow, upper GI done a week ago which showed the following:

Several swallows result in some mild incomplete emptying of the distal esophagus which would represent a pattern of mild dysmotility. There is no fold prominence, stricture nor evidence of a malignancy.

Stomach and Duodenal bulb and sweep are normal.

Impression: Mild Esophageal Dysmotility most probably related to mild esophagitis.

Questions:

1) Would this finding be the cause of my swallowing problems and if so why?
2) Does this Upper GI test show my throat muscles too so if I had a problem with my pharynx this would show up, thus this is exclusively an esophageal problem?

My worry is that this is a neuromuscular problem such a ALS.

Thanks.
