To preface this, I've recently gone to an ER twice and had my heart, lungs, and blood work checked out and everything is perfect, but I was diagnosed with generalized anxiety disorder. I'm a bit of a hypochondriac and what I'm feeling is far from perfect. It's like this burning, pinching sensation just left of my sternum. Sometimes it moves to the center, sometimes to the right, sometimes in my back?! But usually on the left side. Last night after I ate something, I got this real intense burning pain almost all throughout the left side of my chest which got worse with deep breaths. so if it's not my lungs or my heart, what exactly is going on?

I've had this pain for almost a year now by the way
