Black toenails: Black toe nails most commonly refer to subungual hematomas (a bruise under the nail) from trauma. Other causes of black toenails--not from trauma-- could be from severe nail fungus (rare), or from a malignancy (melanoma) --also rare-. If several nails are affected, this suggests subungual hematomas, and can be caused by bumping your foot, by running, or even wearing tight shoes (w/ tight toebox).

Answers include: Possible lint from sock, blood, normal variant or possible melanoma. Should be examined by a doctor. The latter is dangerous.

Black line: The black line could be from a number of causes but play it safe and get a small biopsy. I have seen melanoma from one case the others were fungus or subungual hematoma.

Depends on the color: And direction. Transverse white lines can be fungal or a minor injury; longitudinal white lines may be damage to the nail plate; a dark line can be normal, especially in dark-skinned people, or it could be a melanoma. There needs to be more information and examination to answer more accurately.

From injury???: You can just leave it alone and sooner or later it will just come off on it's own. A new nail will grow in. If it hurts, have it removed by a podiatrist.
