I had an argument with a family member days ago (that got me very worked up) and 2 hours after I started getting heartburn-like feelings in my chest which progressed to constant chest tightness for days. It went away for almost a day then came back. It feels better when I lay down and my back/shoulders are not as tense. 

Anyone go through the same thing? Is there anything I can do to feel a little less tense or lessen the tight feeling? I just want it to go away. This past year i've been feeling all kinds of physical anxiety symptoms and this is a new one. :(
