The skin on our hands and fingers are the most sensitive areas of our body. We use our fingers to feel and touch many things, that's why these areas are densely innervated. Because they have a greater concentration of nerves, we feel more pain when many injured nerves send pain signals to the brain.
Paper cuts are usually shallow and near the surface of the superficial layer of the skin that is densely packed with nerves. A superficial paper cut is usually too shallow to draw enough blood that contains the plasma that assists in clotting that seals the open wound. Hence, the paper cut wound remains open and the injured tissues are exposed. We also tend to rub on the wound unintentionally because it is almost unnoticeable, and these injured nerves will keep sending pain signals to the brain.
