How to treat itchy small blisters on the hands

Generally, small blisters and itching on the hands may be caused by environmental factors, excessive washing or irritation, fungal infection, eczema, allergic dermatitis, and other factors. Depending on the situation, general treatment, medication, or other methods may be used for treatment or relief. It is recommended to seek timely medical attention, identify the cause, and undergo symptomatic treatment under a doctor's guidance. A detailed analysis is as follows:

1. Environmental Factors: A hot, humid environment may promote bacterial or fungal growth on the hands, subsequently causing small blisters and itching, which may be accompanied by symptoms such as redness, swelling, pain, or peeling. It is recommended to keep the hands clean and dry and avoid staying in hot, humid environments for prolonged periods.

2. Excessive Washing or Irritation: Overuse of detergents, frequent hand washing, or contact with irritating substances may damage the skin barrier on the hands, leading to small blisters and itching, sometimes accompanied by mild pain. It is recommended to reduce the frequency of hand washing, use mild and non-irritating detergents, and keep the hands moisturized.

3. Fungal Infection: Fungal infections can cause skin diseases commonly seen between fingers and on the palms, presenting as red patches, small blisters, and itching, which may be accompanied by symptoms such as flaking or thickened skin. Patients may use antifungal medications such as naftifine ketoconazole cream, terbinafine hydrochloride cream, or luliconazole cream under a doctor's guidance.

4. Eczema: Prolonged exposure to external irritants may trigger eczema on the hands, causing the skin to become dry and sensitive, forming small blisters and itching, accompanied by symptoms such as redness and swelling. Patients may use medications such as clobetasol propionate cream, zinc oxide ointment, or calamine lotion under medical advice.

5. Allergic Dermatitis: After contact with allergens, the skin may develop an allergic reaction, presenting as red patches, small blisters, and itching, which may be accompanied by symptoms such as dryness, flaking, and cracking of the skin. Patients may use medications such as cetirizine tablets, boric acid solution, or fluocinonide cream under a doctor's guidance.

Maintaining good lifestyle and dietary habits, avoiding excessive fatigue, and refraining from consuming spicy or irritating foods can help promote recovery.
