Why does the newly formed skin after a laceration still hurts specially if it’s in a part of your body that requires skin elasticity? This is past the scab healing period when there is new pink skin and the wound is totally closed

Question

For instance, if you cut your finger right on the knuckles.

Answer 1

Because new skin isn’t normal skin.

Your normal skin actually has several layers of dead skin cells between the healthy fresh skin and the harsh outside environment.

New skin after a cut doesn’t have that extra protective covering, meaning that sensitive skin is just exposed to the outside world. That new skin is the same kind of skin that is exposed when you skin your knee but don’t actually bleed/break the skin.
