Onychomycosis, more commonly known as toenail fungus, is a progressive disease that is often ignored due to the lack of pain or other symptoms during the initial stages. Typically it is caused by tinea species (fungus), but it can also be caused by candida species (yeast).
Black-and-Blue Toenail Symptoms. The big toe is most often affected. Bruised, broken blood vessels cause the black, blue, and deep purple colors under the nail. Particularly with a blood blister, the fluid buildup can irritate the toe itself causing it to redden, swell, and throb.lack-and-blue toenails are caused by an injury to the skin beneath the toenail. As blood and fluid collect beneath the nail plate the nail itself, which is somewhat translucent, begins to appear black.
