I'm just worried it's not a permanent fix. Every day, I get this feeling in my chest, that used to mean I was about to have a very hard time breathing - one of the vaccine symptoms - and I can get rid of it by working out. So I work out for an hour every day, and it feels like I'm pushing something horrible out of my chest. But if I don't work out... Very bad day.

How long ago have you been vaccinated? What are the symptoms besides shortness of breath? It's funny that for me it's the opposite - any effort worsens the situation, that is, I will have a very bad day 12-24 hours after the workout and it will take at least a week to recover.
