What Should I Do About Itchy Blisters on My Hands?

Blisters on the hands accompanied by itching may be caused by skin problems such as eczema, contact dermatitis, or dyshidrotic eczema. Treatment methods need to be determined based on the specific cause, including avoiding exposure to allergens, medication therapy, and proper care.

1. Analysis of Common Causes

Allergy or contact irritation: Exposure to chemicals, detergents, metals, and other substances may cause the skin to have an allergic reaction, forming itchy blisters. In this case, it is best to quickly identify and avoid exposure to potential sensitizing substances.

Dyshidrotic eczema: In summer or humid environments, impaired sweat secretion may lead to small blisters on the palms, usually accompanied by itching.

Eczema: Eczema is a chronic skin inflammation that may be caused by immune system issues or genetics combined with various environmental factors, often manifesting as redness, swelling, blisters, and peeling.

2. Targeted Treatment and Nursing Measures

Medication therapy: 1. Topical medications containing calamine, such as calamine lotion, can be used to relieve itching and inflammation. 2. Glucocorticoid creams like desonide cream can reduce skin inflammation, but caution should be taken not to use them over a large area for an extended period. 3. If itching severely affects sleep or daily life, antihistamines such as loratadine tablets can be taken under a doctor's guidance.

Avoid irritants and allergens: Reduce exposure to potential allergens, including detergents, soaps, and metallic objects like jewelry and bracelets, and develop the habit of wearing gloves while working.

Daily care: Maintain hand hygiene, avoid scratching blisters to prevent bacterial infections; apply moisturizing cream appropriately to alleviate dryness and enhance skin barrier function.

3. Seek Medical Attention Promptly in Severe Cases

If the blisters cover a large area, the fluid inside is yellow or pussy, or there are accompanying symptoms of fever, it may be caused by bacterial infection and requires prompt consultation with a dermatologist. The doctor may conduct further examinations such as fungal tests, allergy tests, and prescribe oral antibiotics or special creams for treatment.

Although blisters on the hands accompanied by itching may be relatively minor skin problems, they need to be handled based on specific causes, avoiding scratching and irritating the skin. If the condition does not improve or recurs over a long period, it is recommended to seek medical attention promptly to determine the underlying cause and adopt a more professional treatment plan.
