What does it mean when small blisters appear on the hands and cause itching?
Disease description:
My hands have been itchy for the past few days, and there are also small blisters. It feels somewhat similar to athlete's foot. May I ask what causes small, itchy blisters on the hands?

Dr. Wang Xiaoyan
Small blisters appearing on the hands accompanied by itching may be caused by several factors, including:
1. Dyshidrotic eczema: Related to contact with allergens or fungal infections, patients may develop small blisters on their fingers, accompanied by intense itching.
2. Allergic dermatitis: Due to sensitive skin, contact with irritants such as animal fur, dishwashing detergent, or disinfectants may trigger an allergic reaction, leading to small blisters and itching on the hands.
3. Eczema: Possibly associated with abnormal immune function, genetics, allergen exposure, and other factors, patients may develop red rashes, papules, itching, and oozing on their hands.
4. Tinea manuum (hand fungus): Caused by a fungal infection, patients may experience skin flaking, blistering, dryness, and itching on the hands.
