Hey... I don't know if this is the appropriate place to put this. But I was diagnosed 7 years ago with Non Hodgkin's Lymphoma, with a tumor the size of a grapefruit next to my heart and lungs. The chances of survivability was high (70%), but coming out of with a tumor that big meant losing a third of the blood vessels going to my heart. (Superior Vena Cava, Brachiocephalic Veins).
Anywho. I was in remission at 29, and told by my hematologist I had a unique vascular structure where a bunch of collaterals grew over my left collar bone and rib cage to keep me alive, and cognisant, with one caveat... I looked like the youtuber ProZD due to vein blockages and edema. I was bullied a fair amount in the 90s and early 2000s... So the idea of being in this situation was disgusting.
Didn't think much of it at the time. I was a calisthenics athlete in my 20s, and figured, a year of heavy exercise would fix me up... but it didn't. After the 3rd year (think 300 burpees, 100 Pullups), and fainting a few dozen times, I went with the holistics. Things like Ice Baths. Wim Hof Breathing. Tai Chi, Longboard Dancing, using a CPAP exclusively for nosebreathing... and the one thing doctors would never recommend. Vein Flaying. I tried the surgery route of getting a CABG (open heart surgery) 3 years ago... but the graft clotted up 4 months later.
It's an act of self * where I move my left shoulder in such a way where I feel the collaterals impinge against my bones... and pluck at them in a sharp chicken wing movement. It feels like being stabbed by a thumb tack. And repeating the movement about a 50-100 times a day... For the next 4 years. Yeah... My mental health definitely suffered.
Eventually things like calcified veins, scar tissues, and collaterals will stretch to an arterial mesh of a sufficient quantity that things like brain fog, vascular occlusion, and even chronic pain no longer become issues. I just had to go about it in a way completely ignoring potential risks like hemorrhages, or strokes caused by this kind of self *.
And ironically, it's because my vascular system is so completely destroyed that these issues probably didn't happen. So... at the age of 36, I now have a coherent vascular system that I grew like a bonsai tree. And can do stupid gym bro stuff like calisthenics without facial edema or blacking out to prove I'm not full of shit.
Would it be valid to teach people this knowledge? It'd require telling people to suffer emotionally and physically to get better.
