Shift your free hand to the top of your belly and slide it down the side to feel for the baby's back. If that side is smooth and has even resistance to pressure, that's the back. If you can press in further, it's uneven and you feel a lot of movement, that's the front of the baby.
An injury â Bruising or a collection of blood under the toenail can cause the nail to appear dark with black, blue and purple shades of color. Often called âRunnerâs toeâ itâs caused by an injury or trauma to the toe. Cancer â A scary thought but it is a very rare condition. Cancer occurring in the nail bed and the surrounding area will show up as dark, tan and or black spots underneath your toenails or fingernails.
Fungi are capable of producing many colors, and the species that invade nails and cause a discolored toenail are no exception. In laboratory culture, the so-called dermatophytes are predominantly yellow, mahogany brown, or reddish, while saprophytic fungi that invade nails are often green, black or brown, or colorless.ther possible explanations would include a recent blow to the tip of the toe, causing bleeding and blackening under the nail, bacterial growth beneath the nail (often a green color), continuous use of nail polish on the nail, or some other uncommon medical condition. The problem, however, is usually fungus.
