Skin conditions like psoriasis, dermatitis, scabies and hives, internal diseases like liver and kidney disorders, diabetes, iron deficiency anemia, irritation
and allergic reactions to chemicals, wool, soaps, cosmetics
and certain foods can cause itchy skin.
You can apply an anti-itch cream or lotion to the affected area. Oral antihistamine, such as Benadryl can also be used. You should take a comfortably cool bath and wear smooth-textured cotton clothing.
