Definition
Itching in the hands is a symptom that can occur during various conditions.
Different types of dermatitis cause this manifestation, associated with other skin lesions.
The itching can be caused by contact dermatitis, inflammation triggered by the interaction of the palm or fingers with irritating substances or allergens (eg plants, animals, chemicals and drugs such as penicillin, aspirin and sulfonamides). In addition to a more or less intense itchy sensation, this reaction can cause burning, redness, wheals, swelling and blisters.
Atopic dermatitis manifests itself, on the other hand, with severe itching, associated with patches of erythema on dry skin.
Other skin diseases that can induce this sensation in the hands include psoriasis, dyshidrosis (or dyshidrotic eczema) and various infections (eg chicken pox, dermatophytosis, etc.). Other causes include chronic lichen simplex (or neurodermatitis), bullous pemphigoid and scabies.
When it is transient, itching in the palm or fingers may simply depend on an insect bite, a dry state of the skin (xerosis) or excessive sweat production.
If persistent, however, this symptom could signal the presence of a systemic pathology, more commonly allergic reactions to food or drugs, cholestasis and chronic renal failure. In these cases, itching may appear with or without cutaneous manifestations. Other causes include circulation disorders and blood pressure problems, endocrine and / or thyroid disorders.
Furthermore, itching of the hands may be secondary to diseases of the nervous system, liver diseases, Hodgkin's lymphoma and polycythemia vera.
