Psoriasis is a skin condition that happens when the cells grow too fast and build up on the surface of the skin. This condition is long lasting and usually hereditary, explains WebMD. Other symptoms of psoriasis include patches of red skin or silver scales, swollen and stiff joints, or soreness of the affected area. Elbows, knees, the lower back and the face may also be affected by psoriasis.

Eczema is a broad term applied to skin conditions that cause inflammation. One type of eczema, dyshidrotic dermatitis, affects only hands and feet, according to WebMD. In addition to itchiness, other signs of dyshidrotic dermatitis include clear blisters, red and cracked skin, or scaly skin.

The human itch mite is the source of scabies, explains WebMD. The tiny bug burrows into the top layers of skin and lays eggs. Scabies have the tendency to spread in overcrowded areas where there's a lot of skin contact. Itchy hands or feet are associated with infants and kids with scabies. Scabies may also cause itching of the entire body or a pimply rash.
