What's the matter with the black vertical lines on the thumb nail

Black vertical lines on the thumb nail may be caused by multiple reasons such as nail matrix nevus, onychomycosis, malnutrition, etc., which can easily cause abnormal stripes on the nails.

1. Nail matrix nevus: It is usually a benign pigmented nevus, which can easily cause black stripes and vertical lines on the nails. It usually does not affect the health of the nails and life. If it grows faster and covers a larger area, it can be removed and treated through open surgery.

2. Onychomycosis: It is generally caused by infection, which can easily cause the nails to turn black and have black stripes. It may also cause serious consequences such as yellowing, thickening, and hollowing of the nails. Antifungal ointments can be used for treatment, which is beneficial to control the progression of the disease and prevent the nails from falling off.

3. Malnutrition: Nail malnutrition is likely caused by long-term lack of trace elements and other reasons, which will cause symptoms such as color changes and stripes on the nails. It is necessary to cooperate with the doctor to use nutritional drugs to improve.

You should take good care of your hands and nails on a regular basis, and eat more fruits and vegetables, which are rich in vitamins, minerals and trace elements, which can help speed up nail recovery and prevent the continued worsening of local nail nutritional deficiencies. Avoid eating spicy and irritating foods during treatment.
