Proper grooming is the first step in preventing ingrown nails.
Soak the feet first to soften the nails. Always cut the nail straight across using nail clippers, and leave enough nail to cover the toe to protect it. (Do not use scissors, which are difficult to manipulate in the corners of the nail.) Smooth sharp edges with an emery board.
Acrocyanosis is blueness of the extremities (the hands and feet). Acrocyanosis is typically symmetrical. It is marked by a mottled blue or red discoloration of the skin on the fingers and wrists and the toes and ankles. Profuse sweating and coldness of the fingers and toes may also occur.
Acrocyanosis is caused by narrowing (constriction) of small arterioles (tiny arteries) toward the end of the arms and legs.
