it's actually the compressed nerve that's responsible for the numbness, not the loss of blood flow.

Yeah, if it was actually cutting off the blood flow, you'd have bigger problems
What's that phenomenon where as a child you were told a "fact", internalised it, and lived your life presuming it was true until someone points out how obviously wildly untrue it was that you momentarily question reality?
Because I was today's years old when I realised how ridiculous cutting complete blood flow would be. Thank you (genuinely!)
That's called being human, I guess. Our brains wouldn't be able to function if we didn't outsource most of the processing power to the subconscious assumptions
There's gotta be some partial decrease in circulation, though, given that my fingers on the numb hand are usually colder than my non-numb hand when this sometimes happens to me.
Maybe. Could be the compressed nerve reduces vasodilation in your fingers. Could be that your finger only feels cold.
I remember waking and trying to move my arm while it hung limp like a piece of meat. It was horrifying but then came crashing pins and needles after a very long minute.
Used to call asleep with arm under my head face down. Arm would be totally numb and it'd wake me up. Flip over onto my back and hit myself in the face with my giant limp noodle arm.
I've done that to both arms simultaneously. Geez I hope I don't gotta get up for an emergency
