Hey everyone, this is my first post on here so I hope I’m doing it right. 

For the past 3 weeks maybe, I’ve been experiencing shortness of breath and some back and chest pains.

I’ve had panic attacks before, starting when I was ten. The last time was when I was 16 (I’m 20 now).

The shortness of breath is what’s troubling me the most, however here’s the annoying part. I can breathe a deep breath, however it feels like I’m just not getting enough oxygen and I’m starting to worry that maybe it’s more than anxiety? It lasts for a couple of hours and I can still move around but it’s still troubling.

The back and chest pains aren’t too painful and don’t last for that long, but they’ve been persisting for 3 weeks and come on and off.

I’m asthmatic and I smoke (I know, I’m stupid and I’m trying to quit) and I am worried about covid. However these symptoms don’t really come on when I expect them to. 

Could this still be anxiety or something else?
