What is black plaque appearing on toenail to return a responsibility

Black patches on toenails are first considered to be caused by internal bleeding caused by trauma or impact. If this condition is not very serious, it does not need special treatment. However, if it is serious, the nail should be removed in time to drain the blood stasis inside. Black patches on toenails may also be caused by fungal infection caused by the patient's lack of hygiene. This condition requires treatment with antifungal drugs. If treatment is not timely, it may cause infection on other nails. It is recommended that patients pay attention to personal hygiene and change shoes and socks every day.
