What is the disease that causes black spots under the fingernails?

Fingernails all look pink. Of course, the color of some people's fingernails may change for various reasons. However, if the color changes again, it will still be close to pink. If the color changes significantly and even there is some black inside the fingernails, this is too abnormal and may be related to a certain disease. So the question is, what is the reason for the blackening under the fingernails?

Onychomycosis: Don’t think that all onychomycosis is gray, in fact, some are also black. It manifests as thickening of the nails, or hollowing out of the nails with white powdery substances. Oral antifungal drugs can be used for treatment, but the risk is relatively high. The best way is to use a packing treatment.

Subungual bruises: Subungual bruises are common and are often caused by squeezing or collisions. Bruise under the toenails is sometimes caused by wearing high heels, standing or walking too much. This condition usually doesn’t need to be taken care of and will naturally improve after a few months.

Nail matrix nevus; this type is also not uncommon; it often appears as a bundle of lines from the nail root to the nail tip; it is generally harmless to the human body; sometimes it develops into nail pigmentoma;

The nail matrix nevus should be closely observed. If it is found to be getting bigger or bleeding, it is considered to be a nail pigment tumor. You should go to the hospital to remove the nail in time, surgically remove the subungual tumor and do a pathological examination.

It indicates respiratory problems. In fact, it is blue (looks black). This type of person is prone to cardiovascular disease.

It should be noted that there are no nerves or blood vessels in the nail plate, so it will not bleed. The so-called subungual bleeding is actually bleeding under the nail.

Regardless of the type of nail darkening, vitamin supplements are beneficial.
