Causes of Blisters on the Hands

Blisters on the hands can be caused by eczema, friction injury, chemicals or allergens, medication reaction, infections, burns, or diabetes.

Blisters are fluid-filled bubbles that appear on the skin, containing blood, pus, or serum. It’s advised not to pop blisters to prevent infection.

Blisters on the hands can be painful and uncomfortable, caused by friction, irritation, infection, or underlying conditions.

Signs and symptoms of hand blisters

Hand blisters are easy to identify, appearing as small, medium-sized, or large pockets of fluid on the skin’s surface, usually on the palms or fingers.

These blisters can be painful, itchy, and scaly around the affected area.

Types of hand blisters

The main types of blisters are heat blisters, cold blisters (chilblains), and friction blisters. Other types are related to underlying health conditions.

Causes of hand blisters

Dyshidrotic eczema

Blisters on the hands can be caused by dyshidrosis or dyshidrotic eczema, appearing as small, itchy blisters on the palms, fingers, and soles of the feet. This condition is temporary and lasts for a few weeks.

Friction

Friction from objects can cause blisters, such as working with a rake without gloves.

Irritation

Chemicals or allergens can irritate the skin and cause blisters. Nickel-rich foods have been associated with hand blisters.

Medication

Some prescription drugs may cause blistering reactions. Consult with a doctor if you experience blistering after taking medication.

Infection

Blisters on the hands may indicate other conditions like chickenpox or impetigo. Consult a doctor for further evaluation.

Burns

Blisters can occur from severe sunburn, contact with hot surfaces, or exposure to flames.

Cold

Extreme cold can lead to chilblains on the fingers, causing itchy red swellings that may develop into blisters.

Diabetes

Severe diabetes can cause blistered hands or forearms, which usually heal on their own.

When to see a doctor for hand blisters

Consult a doctor if blisters persist and if you haven’t had a tetanus injection in over 10 years, experience swollen lymph nodes, increased swelling and pain, or signs of infection like pus, redness, or fever.

Diagnosis of hand blisters

The cause of hand blisters is usually apparent. However, a doctor may inquire about family and personal medical history, allergies, medications, chemicals, or allergen exposure. Patch tests or skin examination may be conducted in some cases.

Treatments for hand blisters

Treatment depends on the underlying condition. If the blister hasn’t popped, cover it loosely with a bandage. If it has, wash the area with clean, warm water and mild soap without removing the skin flap. Cover with a sterile bandage.

Treatments may include draining large blisters, antihistamines, anti-itch creams, or immune-suppressing ointments. It’s advisable to seek medical advice before attempting to drain blisters at home.

How to treat finger blisters

If a blister isn’t painful, leave it intact for protection. Cover it with an adhesive bandage or moleskin. If the blister is painful, follow specific steps to drain it without breaking the skin. Apply petroleum jelly or ointment, and monitor for infection.

Caring for a finger blister

Do not pop the blister if it’s not painful. Keep it clean, cover it with a bandage, and consult a healthcare professional if you have diabetes or symptoms of infection.

Prevention of finger blisters

Prevent friction blisters by wearing gloves for labor or well-fitting clothes. Avoid pinching your skin to prevent blood blisters. Prevent heat blisters by using sunscreen and taking precautions near hot surfaces. Consult a doctor for immediate attention if you have diabetes and notice blistering.

Healing time for blisters

Most blisters heal within a few days. Cover them with a bandage and consult a doctor if signs of infection occur. Seek immediate medical attention for severe pain, swelling, or redness.
