What's wrong with a black nail?

Generally speaking, a sudden black spot on the nail is related to blood stasis. The most common reason for this situation is that the nails may bleed due to bumps or collisions in daily life, and if you don't pay too much attention to it, after a period of time, the red blood will accumulate and turn black. In fact, in this case, we don't need to worry too much, because the blood clot will fall off after a period of time, and then a new nail will grow.
Another reason that causes a black patch on a nail is due to lack of nutrition in our body. As we all know, nails are actually made up of protein. When our bodies lack protein or calcium, black spots will appear on the nails. If this happens, we just need to replenish nutrition in time and eat more foods that can nourish the body. Another possibility is that due to paronychia, there are skin problems. In this case, you can go to the hospital for a check-up.
