Blisters on itchy hands after scratching may be caused by ringworm, eczema, and unusual type of aspergillosis.
1. Ringworm: If you are in close contact with people with fungal infections, or in a hot and humid environment, it may lead to fungal infections and cause blisters on itchy hands.
2. Eczema: If the hands are often in contact with irritating washing products or objects, such as washing powder, detergents, skin care products and other chemical products, an allergic reaction may occur, resulting in blisters when itching and scratching the hands.
3. Ordinary-type pemphigus: Ordinary-type pemphigus is an abnormal symptom caused by the presence of antibodies that destroy intercellular links between epidermal cells, which may lead to blisters when itching and scratching.
Patients who have blisters after scratching itchy hands should go to regular hospitals in time to clarify the cause of the disease and take targeted treatment measures under the guidance of professional doctors.
