First of all, sorry for another post! Secondly, I apologize for resorting to the enemy of society, Google. Unfortunately when I did, I found these:
And guess what? I can't belch. I have a tight chest that occasionally hurts. My back/neck hurt sometimes too. Even worse, I have a lot of abdonem/chest burning, often after exercise or more often after eating. I really want it to be indigestion from anxiety or a side-effect of Diazepam, I really do. I just can't believe it, especially after trying an NHS symptom-checker which says I need my heart checked, which I can't do until January 9th.
Please please please tell me other people experience this sensation; I'm in tears about potentially dying.
