Welcome to HCM
We understand your concerns
The pain around youe esophagus
could simply be gastric derangement because it started during food intake. The gastric symptoms could well be travelling to left shoulder or back. Also think about some tiring work the previous day of the incident.
Also you seems anxious about the problem. Therefore it is always better to consult a General Practitioner and confirm there is nothing to worry.
Get well soon.
