Should I go to the doctor?, This happened 2 days ago, I can kinda breathe, not labored,but my chest hurts when I do so.
I would also like a legitimate answer, This already worries me.
Maybe your lungs are irritated from the helium. Bronchitis can be caused from irritants like smoke dust and maybe helium. You maybe triggered an asthma attack. There are many possible reasons. I think you should see your doctor but I don't think that it is life threatening. Just go as soon as you can to find a solution.
You should be worried that you're stupid enough to have this problem.
