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”.
In: Biology
Chronic pain is often associated with an increased pain response called hyperalgesia. This is thought to be due to your brain and nervous system going into a state of persistent high-reactivity after experiencing pain. Once this happens, your body can actually perceive pain even when the initial insult is gone.
