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

673 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”.

Maybe because the chronic pain is intermittent?

I’ve had an ankle injury that flairs up every few weeks, and is always a little tender and gets sore on any kind of walk or especially if I jump or lose footing. But if I’m just sitting on the couch or laying in bed, it doesn’t really hurt usually.
