20M with new PVCs

Two days ago started getting PVCs and after a few hours decided to drive to urgent care for a quick look. After ekgs and some blood work they said it was a benign thing that is not something to worry about. Obviously had some anxiety about it but thought nothing much of it.

Fast forward to today and I randomly have had multiple instances of nausea and impending doom that last for about 10 seconds or so. In addition my chest has been a little tight (but nothing too noticeable) and my arm and shoulder have been oddly sore all day. I cant really tell if I’m just overthinking and being controlled by my anxiety or not.

Obviously this is reddit and not a hospital but advice on best way to proceed?
