I had a heart transplant 9 months ago and wear a mask outside in our neighborhood, at the local lab location, on the episodic trip to the grocery store or Home Depot. I have had no issues with wearing a mask at all. Therefore my single data point offsets your single input and then we can conclude there is no issue, right? LOL. I am sorry wearing a mask brings you so much discomfort. To what extent does anxiety play an issue in your feelings which are clearly real to you?
