, I'm sorry that you may be feeling this type of pain right now. It's important to report this to your doctors because it may or may not be the MS hug, or esophageal spasms, or something heart-related. There are so many possible causes of chest pains.
I do see (now) that you posted this originally last summer. Did you ever learn what caused the pain? I hope that you are doing well now.
