I had some recent heart issues (no physical issues but something looked odd on an Xray) - and I learned something about myself. I didn't really give much of a shit. I took my sweet time scheduling the recommended diagnostics and then I took my sweet time following up on it.
The doctor actually phoned me after the tests and told me to come in and it wasn't until I was sitting there in the office that I thought, 'Oh yeah, this is about heart stuff and the doctor has told me to come in which usually means there is an issue. Maybe I should start being concerned.'
I guess I am the opposite of a hypochondriac.
Anyways, sorry, didn't mean to make this about me. Better to have some urgent concern as you do. Hopefully (like me) it will end up being basically nothing.
