We all feel physical pain due to nociceptors in our skin, but there’s a certain rare condition in which you can’t feel any type of physical pain for any reason. Is there any specific cause(s) of the condition? Can you develop it somehow?
In: Biology
There are instances of this when you transplant organs. Such as the heart. You will not feel pain (say during a heart attack) because the nerves were severed. Burns that damage nerve endings also can cause analgesia (no pain). Think of the nerve endings like electric supply lines. They stretch for a while until they hit a relay station and are bundled together before moving up the line further. They continue bundling until they hit their origination point. If you cut them at any point, no pain transmission. Damage to the spinal column (the posterior and lateral portions) can also cause this in areas below the level of damage.
As for this coming on like an illness one day? I’ve never heard of that or read about it.
It sounds like you’re talking about congenital insensitivity to pain, which is an extremely rare genetic disorder that causes people with the specific genetic mutations to feel little or no pain. It’s genetic, meaning you are born with it. It’s impossible to develop it later in life.
