Nail fungus can cause the nail to become thick or ragged and appear yellow, green, brown or black. An infected nail may separate from the nail bed. Nail fungus is a common condition that begins as a white or yellow spot under the tip of your fingernail or toenail. As the fungal infection goes deeper, nail fungus may cause your nail to discolor, thicken and crumble at the edge. It can affect several nails.
