Fungal infection: It looks like you have fungal infection of the toenail. It requires long term (couple of months )of antifungal treatment since it is tough for the antifungal medicine to penetrate and destroy the microbe. In any case i advise you to see your pcp, he /she may take some sample or treat you empirically.

Agree w Dr. Zebro. Can also see a podiatrist for this (or even dermatology).

Hematoma: It sounds like a subungual hematoma . This happens usually from injury from injury to toe. Reddish blue is most likely active bleeding and black is old. The green is concerning. It should be evaluated for healing/infection. There are some bacteria that turn things green so you should see a podiatrist to evaluate. Healing bruises also turn many colors. The bruise has to grow out.

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.

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.

Toenail: If he is an avid runner we see this often due to the recurring trauma.He may also have a fungal infection. He should be evaluated to make sure it is not an internal issue as well.
