Hey everyone. 25M, I lift / exercise 4x a week. Moderately decent diet. Been having on and off chest tightness for about two years now. Sometimes it’s accompanied by pain. 

First time I went to the docotor — nothing, cardiologist — nothing. Even said they couldn’t detect any blocked artery. About a week or so ago, I started experiencing chest tightness and shortness of breath again. 

Went to the doctor a few days ago — nothing. Got an X-Ray done — nothing. Going to see cardiologist again on the 27th, I’m sure he’s gonna say there’s nothing either.

What exactly is this then? I’ve been unemployed and been kind’ve worrying about money etc, but nothing really major. Can stress or anxiety actually cause chest tightness, shortness of breath, and slight chest pain?
