hello, I am a 26 year old male. i've been having weird symptoms the past couple years, but now that I think about it i've had flashes of them since I was little. I fainted twice in highschool around ages 15/16. When my parents took me to the hospital after once passing out in the hot shower the docs found nothing wrong except that I had some orthostatic hypotension which they thought wasn't severe at all. Nothing was done about it, and although I regularly would get dizzy on getting up too fast I didn't really pass out again until my 20s. throughout college there would be some days where I would go lift at the gym and be unable to finish my workout due to how lightheaded/sick id feel after each set, but it didn't happen too often so I ignored it. ->Fast forward to age 24 I start getting this on and off feeling of air hunger every once and a while. Palpitations would occur too. at 25 it was happening more consistently. Since early 2020 I Have rarely been able to get through a workout at the gym or a hard run without getting dizzy, super out of breath, and my heart pounding out of my chest. a few times I Almost passed out doing a mile run at around 7/8 minute pace. my heart was beating out of my chest and I quickly got myself to the floor before I would have fainted. This led me to see a cardiologist for which I did all the tests (EKG, stress test, echo, holter) all coming back normal. my cardiologist seems to think I have some type of dysautonomia as does my girlfriends dad who is a physician. just to hit my bases i'm seeing a pulmonologist soon as well. Does this sound similar to anyone elses situation? Just curious. I'm scared to even workout now or run hard from fear of my heart getting erratic and breathlessness that makes me pass out. After Every set at the gym it feels as though no matter how much I gasp for air im not getting enough. It really sucks and its been bumming me out a lot seeing how I was a solid athlete just a few years ago :(. sometimes a brisk walk even brings on the feeling of air hunger. Thank you for your time and for any responses.
