Why does a paper cut cause so much pain?

For example, a sharp razor blade makes a smooth cut without leaving foreign particles in the wound. And although such a cut causes pain, these unpleasant sensations usually disappear after a few minutes. And a sheet of paper, in addition to making a cut, does other minor damage with the help of microscopic fibers in its structure.

In addition, during a paper cut, particles of these fibers and other foreign materials remain in the wound, which constantly stimulate pain receptors in the skin at the edges of the wound. In turn, the large number of receptors increases sensitivity, and a person experiences pain even with minor injuries.

It is also worth noting that because a minor cut does not bleed much or not at all, the blood does not “flush” foreign objects out of the wound, and new stimuli enter it. All of this causes a person more prolonged pain than, for example, from minor bleeding wounds in other parts of the body.
