Why Are Paper Cuts So Painful?

Paper cuts, though small, are painful due to their occurrence on hands, which are rich in nociceptors. These cuts damage the epidermis, sending strong pain signals to the brain. Paper's jagged edges exacerbate the injury by tearing skin cells and leaving irritants. The lack of bleeding prevents scab formation, prolonging pain and healing time as hands are frequently used, causing the cut to reopen and get dirty.
