I used to get excited with mystery patients.
Like a patient would come in with a super low hematocrit and we had no idea why, and I'd actually be curious to figure it all out. Unravel the mystery, so to speak.
Now I'm jaded. I've realized we often never find a good answer to those mysteries. Like at the beginning of my intern year, I had a young healthy patient who spontaneously went into heart failure and nobody ever figured out why, despite the fact that I sent a huge viral panel.
It's sort of like when I used to watch X-Files, back in the day... there would be some really interesting build-up and I'd be really excited to find out the answer to the mystery, but it would always end up being pretty unsatisfying with a lot of loose ends. Ditto with Donnie Darko.
