Hi @globaloutlet, there is a long standing thread with a lot of comments on mysterious shortness of breath, or for me, what I would call 'air hunger' or dyspnea. The feeling like I can't get a deep breath. If that's what you're experiencing, first of all I'm sorry you're dealing with this. It's so hard because breathing is a core function. But this thread has a lot of ideas and what has worked for people and some suggestions of things to look further into such as various doctor tests and breathing exercises to help with the symptoms. https://connect.mayoclinic.org/discussion/mysterious-shortness-of-breath/
