We need fingernails for grip. Fingernails are calcium deposits. Fingernails give our fingers support. If we didn't have them our fingers tips would be too soft to grip things.Fingernails are NOT calcium deposits. They are keratin just like the top layer of skin and our hair. They do help give our fingers support and are meant to help protect our fingertips.Fingernails are a part of the normal function of the body which skin cells die and turn into the hard "nail" that grows constantly on your finger. They serve no known function, but are required for the life cycle of skin cells. This is the so called cemetery for skin cells.
Your fingernails feel painful and red because your skin is attached to your nails.
