I have a thick white line down the length of my big toe that grows as the toenail grows?

Toenail line: You probably had some trauma in the past to the growth plate which nows constructs the toenail with the line. This might be unsightly, but unless thick and uncomfortable, can be ignored. It might be an excuse to get a pedicure with polish if that fits your lifestyle.

Injury or fungus: You may have injured the toenail or you could have a fungus.

Fungal infection?: If you did not hit your foot it sounds like you may have a fungal infection. Usually when it is white it is usually due to the moisture loving fungus Candida... Good news it is pretty easty to get rid of so call your podiatrist

Sometimes: fungus takes the shape like that but it doesn't have to be. A foot doc or dermatologist sometimes can biopsy the toenail if they feel it is warranted.

A 41-year-old male asked:

My big toenail is white on one half and thick. What is it and what can I do for it?

Could be fungus in: the toenail. A doctor or podiatrist can evaluate and tell for sure. Sometimes the nail grows back thick because the nail bed has been damaged. A culture can be taken of the debris below the nail, or but cutting a piece of the nail and sending to a lab. fungus infections of the nail can be treated but the treatment is long and the nail grows slow so you may not see changes for months and months
