@pansies I've had it for the past 4 or so years.. I find that I can go a long time no symptoms or I can go a while with daily symptoms. It's pretty much the same as what u say, Mines mostly in the chest sternum area also. I'll start to cough like asthma when it gets too tight.

@pansies yea same exact symptoms. I am having it since atleast 10 month now. It goes away few weeks and comes back. Avoiding lot of stress heavy work because of it. My dr is giving me high dose of anti inflammatory for now. And doing some heart test as well.all heart test are good so far.
