At some point last month I put my left hand against the headboard behind my head and pushed. (You know that move, you've done that move, I am not ashamed.) A few days later I noticed some mild pain in my left armpit. I figured I had pulled my chest muscle.
Only, a pulled muscle would get better, this pain got worse and kind of marched across my left chest to my sternum over the next few weeks.
I picked out my own working diagnosis, as you do, and I was pretty certain the doctor would say "pericarditis," and I'd feel better just from that.
But instead the doctor said, "EKG," and then, "see this wave and that spike," to which I said, "Someone saw similar waves in 2020," and now I have an appointment with the cardiologist next week.
Much of what I read about my EKG "echoes" one thing the doctor said, which is that I might have previously had a heart attack. This seems impossible. No heart attacks, minor or major. Not unless I'm one of those pets that can sneeze itself into a heart attack.
This is not anything I need right now, that's for sure.
