How To Treat A Black Toenail
Treat Underlying Condition

When a black toenail isn't caused by an injury or trauma, it tends to be related to an underlying condition. Black toenails are often just symptoms of other issues, rather than being their own disease. This means treatment varies depending on the cause. With an injury, as stated, individuals will typically use injury treatments like the RICE method. Fungal infections can be treated with over-the-counter ointments or an antifungal prescription.
However, there are some more serious potential causes of a black toenail. Diabetes can lead to a black toenail when one of the patient's feet becomes damaged due to diabetic neuropathy. Melanoma can also cause unusual toenail discoloration. This type of skin cancer can easily spread and become very deadly if not detected and treated properly. If individuals think they may have a serious illness, they should see a doctor so they can get tested and diagnosed.
