Wow, similar thing for me, I have a 'bicuspid aortic valve' which means the aortic valve in my heart is a bit funky and doesn't push blood through as it should. And that makes the FAA also deem me medically unfit. I think there is a process to get a medical exemption, but with the cost of getting a license so high already, I just decided to stick with MSFS. I get to 'fly' a 737 like I wanted as a kid, learn all about it, but I'm not shelling out thousands and years of my life (okay, maybe I am shelling out some money but I like pretty airports!)
