I have been unable to qualify the pain until last night. I would say it feels crampy or gassy. I am not especially gassy or bloated tho.
I had a massage yesterday and the registered massage therapist was working pretty hard on my upper back on the left side, much more arduously than usual, so I asked him if it was tense and proceeded into telling him about the chest pains. He said chest pains could come from the back as well.
Puzzling and scary. If I can get a definitive diagnosis as not from my heart but muscle or gas or even reflux, I will stop worrying but in the mean time I worry
