I put it short, Castout:

Learning does not hurt. Never. Not physically, and not in a transferred sense.

You will not find any neurologist or brain physiologist in support of that theory of yours. Neurons can establish new connections in neural networks, and in side the brain. But it is not as such a simplified process and not to be accompanied by physical sensations. That olyu are sitting at the table for 6-8 hours, has more to do with it. I occasionally needed to sit at a cashdesk for 6 and 8 and 10 hours, years ago. And although I did not learn anything there and my brain slowed down into coma mode - I also had headaches and felt a drain of concentration and focus after some while and could not multiply 2 and 3 for a correct result of 6 at the end of my shift. The headache could be helped by getting a better chair, and moving a bit if situation allowed, and avoiding cold wind touching my neck.

The only way neurons in the brain can produce pain themselves , is infections. Such diseases are rare, but they are from hell. There is for example an infection by amebas, that overcome the blood-brain-barrier and enter the brain, there starting to eat the isolating myelin sheath of neural axons. The reult is a pain as intense that it floods your consciousness - and cannot be avoided at all, becasue this sensation cannot be redcued by tranquilizers and painkillers, no matter which one - the whole chemical and physicological process by which painkillers become effective, is being bypassed. A disease like this must be amongst the most desparte, hopeless things that can happen to humans, or any organsim with higher brains. It's living hell. You are doomed to live through the most intense pain sensations the nedural network can produc e, all time long, and there is no way to tame it. Even when being put into sleep or artificial coma, the pain sensations still are there.

But learning does not destroy the myelin sheat of axons, thankfully.

Myelin sheats help to increase bioelectrical signal speed along the axons by making the electric potential "jump" from one rupture of these sheats to the next, instead of needing to travel through all the axon between two such points.
