Biopsy: The black spot could be many things, including a blood clot from localized trauma, such as a tight shoe, a fungal infection, or a serious skin condition affecting the nail bed. See your local podiatrist to have it evaluated.

Depends on diagnosis: It could be a fungal or bacterial infection. It could be bruising due to tight shoes or trauma. It could be a pigmentation of the underlying skin. It could be a skin disorder or melanoma, or it could be one of a number of many other possibilities. Have your feet checked out by a professional. Treatment depends on the diagnosis.

Blood.: It is likely to be trapped blood from an injury. However, it also could be melanoma. You should have a podiatrist take a look at it to make sure.
