Hi @cbbmom, welcome to the Lung Health group. It is frustrating when dealing with a significant symptom that seems to have no known cause or explanation. You'll notice that I moved your message to this active discussion thread called "Mysterious shortness of breath". I did this so that you can connect with others, like @gabrielm @merpreb and others who are seeking and finding answers about the shortness of breath and ways to cope.

Having had pneumonia 2 years and COVID a year ago, does the pulmonologist think there may be a connection to post-COVID recovery? While normal test results are good, it makes it hard to find answers. What seems to trigger the feeling of chest pressure and/or the shortness of breath? What gives you relief when you experience these symptoms?
