Full Answer

Psoriasis, a hereditary skin condition, causes the skin to turn red in one or more places. Pus-filled bumps or silver scales may also appear on the skin, states WebMD. Patients with psoriasis also experience swollen or stiff joints and pain in the affected areas. Similar to psoriasis, eczema causes scales to appear on the skin. Patients with eczema also develop clear blisters and red patches on the skin.

In addition to skin conditions, patients with diabetes sometimes experience an itchy rash on the hands and the feet. This rash, characterized by small yellow or red bumps, may also appear on the arms and the legs, claims WebMD. With proper diabetes management, this rash should disappear on its own and should not return.

Patients with scabies, also known as the human itch mite, develop a small, blistery rash and sores on various parts of the body. Itchy hands and feet are more common on infants and children with scabies than adults, reports WebMD.
