If you think the tourniquet technique sounds interesting you should read up on “awake craniotomies” - another very interesting area of anaesthesia and consciousness.

Ultimately in anaesthesia, the mind may not recall the experience but the body still feels it. You see this in unparalysed body’s that flinch when they’re cut, or in fully paralysed bodies that signal pain in an observable increase in heart rate and blood pressure. However, most the time, people are also given substantial analgesics to reduce their likelihood of experiencing pain, but the point I’m trying to make is an unconscious person is still able to feel pain of they have not been given adequate pain relief.

What if the experience of pain is separate to the experience of heart rate rising and blood pressure rising?

Like, you get a cut, and the trigger is the "damage" that then triggers pain and the heart rate rising. It's not the pain itself that triggers the heart rate but the damage. Maybe? Idk

I wouldn't be surprised if it was a little of both.
I've read about something similar called split brain where there can be separate consciousness in the brain and maybe elsewhere. Interesting experiments have been done on it and it just all seems so weird. Very tricky figuring out this consciousness thing from the inside.
