Med School

Anybody else ever feel an existential, constant pull to go to med school? Been a PT 9 years, been in med device the last 4 of those, and just can’t help but feel called to do more. Not sure if it’s just the excitement of it or because I really want to. I think what’s been holding me back is not knowing how to proceed. Wouldn’t I have to start university all over again? I don’t know what prerequisites I’d be missing if I did want to take the MCAT to apply for med school. Any direction or advice would be greatly appreciated. I work in cardiac surgery and really just love cardiology as a whole.
