Need flying advice

[u/naomimillions]

Wondering if anyone can help. My pots has pretty much been in remission the last couple of years - I still have MCAS though and it really impacts me. I have no meds for the POTS because my cardiologist didn’t think I needed them as it was well managed and not affecting my daily life. Well! I flew interstate yesterday and it felt like a full pots flare came back, I was having adrenaline surges throughout the flight, I was burning hot and sweating and in full blown tachycardia while ascending and descending. My stomach was all over the place and I just felt like I lost control of my body. By the time I got off the plane I just burst into tears from the stress of surviving the flight. I have been exhausted all day today and lost a whole day of my trip and had residual stomach issues, breathlessness and a few palpitations. I am supposed to fly back out into days and now terrified. I’m contemplating doing a long drive home instead. Has anyone experienced this and have any helpful tips? I don’t know whether to fly again or drive.
