I thought we didn’t have nerves that tells us ‘this hurts’ inside of us, like brain and stomach.
We don’t feel the liquid that dissolves our food, and yet sometimes our stomach, or oesophagus, guts hurt.
How come ?
Pain is a signal from your body that there is damage. The only reason the brain doesn’t “feel” pain is that it doesn’t have sensory nerves in it, so it can’t sense it’s own damage. Everywhere else in the body has this capacity in some form.
