Itchy hands and feet may be caused by psoriasis, dry skin, scabies, eczema, allergies or diabetes, according to WebMD. Doctors can assess a patient's symptoms to make a diagnosis and determine an effective treatment plan, such as topical ointments, prescription medications, creams, antihistamines, corticosteroids or lotions.
People who suffer with psoriasis are likely to experience chronic itching on the palms of their hands and soles of their feet, explains WebMD. This activity is often accompanied by scaly skin, soreness, redness and itching on other areas of the body, such as the face, knees and elbows.
A specific form of eczema, known as dyshidrotic dermatitis, is localized to the hands and feet and may appear as clear blisters or cracked skin. It is common for people to have allergic skin reactions to substances they come in contact with, signaling another form of eczema known as allergic contact dermatitis. This type of reaction may produce a rash, hives or blisters.
People with undiagnosed diabetes often become aware of the disease when their skin starts behaving in strange ways. This activity, referred to as eruptive xanthomatosis, indicates that the illness has progressed to an alarming level and requires a structured treatment plan to get under control, notes WebMD. Itching associated with eruptive xanthomatosis may manifest on the skin as yellow bumps with red borders.
