Eli5: Why does the body not get used to chronic pain?

669 views

I get why feeling pain is important for us, but why does the body not get used to chronik pain? I dont need to get reminded that my knee hurts for 10 years.

Wouldnt it be smarter if the brain is like: “This nerve is sending me constant signals about pain for years, i should just cut it off”.

It can’t do that. Cutting pain off would also remove your ability to feel things in those places. And that’s very bad, because feeling pain is your body telling your brain something’s wrong. You’d be injuring yourself all the time and not noticing.

And then there are folks like me, who are in constant pain literally everywhere all the time. I wouldn’t even be able to move.

Ultimately, the benefits of being able to feel pain outweigh the negative aspects. Being in pain may be miserable, but not having pain can easily cause you to be harmed or even killed.
