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.

Could be: A normal variant, blood, fungus, melanoma. The concern would be melanoma and hence should be checked out.

Are there any potential complications you could have from tearing off a toe nail?

Maybe: After having a nail (finger or toe) removed or torn off, you need to know the status of the underlying nail bed. If the nail bed has been badly damaged or has not been repaired well, the growing nail may lift off as it grows out.

Possible Fungus: This may be a sign that you have a fungus infection of the toenail (onychomycosis). You should have it checked by a dermatologist.

Treat as wound: Treat the open wound as you would a cut with neosporin and cover to protect it. Then wait for the toenail to slowly grow back out.

It depends: What you describe is a black toenail or subungal hematoma. This can be extremely painful and there can be pressure under the nail from continued bleeding. Most of the time the pain and throbbing improves with rest & ice. The discoloration improves with time as the blood stained nail grows out. However, if the pressure/pain continues or gets worse the hematoma must be drained by a doctor.

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