Finding out about autonomic dysfunction and small fiber neuropathy as I researched my own fatigue and finding out I likely have this has been very challenging.
Please don't do this. It's the medical equivalent of copy/pasting shit you don't understand from Stack Overflow.
Go see a doctor who has a degree and training.
Widespread issues all over the body without readily obvious organ damage is nearly always nerves/brain.
99% of physicians wouldn’t know what to do with specialized test results anyway, even if they’d know what/how to order in the first place. Internists don’t know how to read PET scans, radiologists don’t know anything about homeostasis. general radiology cant even read head&neck scans, you want a specialized radiologist for that. geneticists don’t have the slightest idea about how to read nerve studies, which is actually a completely separate certification, not even every neurologist has it or does them.
Medicine is the game of super-specialization.
And nobody wants to bother to try to piece it all together for you. Very few MDs are actually able to, in the first place.
Ideally, you have a very broadly competent internist to figure out what direction to even start digging at, and then find the sub specialist who has the expertise AND interest in that area.
eg NIH’s section on neuro cardiology recently closed because this one dude who was REALLY into simply was too old, couldnt find a replacement or build a bigger lab that could sustain itself and retired.
At times you need a specialist trained and practicing in two different specialties: eg ENT + neuro, for example. Those can be hard to find. Neuro cardio more common especially now.
I agree with your general thrust of course, you’re much more likely to incorrectly diagnose yourself doing this than correctly, and walking around with a false belief is worse than walking around with uncertainty. But simply saying, “go see a doctor,” is rarely helpful. I’ve never heard of someone who tried to diagnose themselves without first presenting the issue to a physician.
If you sleep over 11 hrs per 24 hours: that’s pathological and they will be prescribed.
Fall asleep faster than X minutes? Same diagnosis, same meds.
Have apnea and yet still fatigued/sleepy after CPAP/surgery? Same meds.
Fulfill criteria for ADHD? Same meds.
Fatigue after TBI? Same meds.
Fatigue with MS? Same meds.
The root cause may or may not be eventually found, but there is no reason to get diagnosed with whatever is most useful to begin at least supporting treatment.
These sorts of conditions are systemic, and the causes and ways of dealing with the accompanying syndromes are probably always going to be different from individual to individual (well, likely the exact physiological causes anyway).
There was a SARS vaccine as far as back 2016 which could have changed everything but was ignored. Pharmaceutical execs told them they were, "waiting to see if it comes back yearly" first
