A couple of days ago I started getting a bit of twinge between my shoulder blades, and assumed it was from carrying a heavyish rucsack to work and back for a few days. Yesterday, I noticed that when I drank I was getting a pain in my chest; more specifically about halfway down to my stomach. It feels like either the tube is narrower or it's inflamed, and so causing me pain. I have had a few digestive (stomach ulcer) issues in the past.
However, today the pain has spread from my back into the right side of my neck and shoulder, and it hurts to swallow food.
I'm guessing (or rather hoping) that this is another digestive issue. Does anyone have any advice please? I've tried Googling but not had much success. Thanks.
