Once your out of stuff you can think to test for modern medicine doesn’t start throwing tests at the wall to see what sticks... it shrugs its shoulders and gives up.

Now sometimes this is good (hypochondria + psychosomatic problems) but sometimes this is bad... failure to get a diagnosis due to skipping something they didn’t think of.

This is why I always tell people who are unsatisfied with the handling of their medical problems to get a second opinion, a third opinion, as many opinions as it takes. If your doctor says they don’t know why something hurts... ask another one. At some point you should press for referring to a specialist... even if it’s a damn psychiatric specialist because they think it’s in your head... when they check you’re not crazy, that’s one less excuse they have for ignoring your problems.

That’s what this person did here. Eventually the only opinions left were the ones they had to dig up on their own. Sometimes this path even involves researching new (or old/forgotten/misunderstood) but at the end of the day this is how hard it is to understand how the body actually works.

It’s one of the reasons I’m so thankful for my reasonably good health. There’s a nearly infinite number of ways the body can be broken or damaged, the fact is we only understand a small part of the most common things that go wrong and can fix an even smaller number of the things we do understand.

Edit to pre-empt criticism of affordability of this approach: I live in Australia where we have public healthcare so everyone can see a doctor (or twelve) without being driven into bankruptcy.

He was able to improve his condition by being on a permenant norad infusion, which is something we only do in hospitals to critically ill patients who are having a hard time keeping their blood pressure in any normal range. Generally, norad is a shorter acting version of adrenaline that acts on a slightly different hierarchy of the same receptors. If it was as simple as ‘too much’ adrenaline, I suspect some benefit effect would have been seen by beta blockers. Maybe there is, maybe that’s one of the 9 medications he takes every day.

Worth noting also that a condition that dumps way too much adrenaline into the body, phaeochromocytoma, is often an incidental finding; so this obviously presents differently despite having (simplistically, from the article) the same type of mechanism.

We don’t have all the information we need to make inferences from this particular article
