The appearance of blisters on hands can have various causes, including different medical conditions. The blisters are filled with a clear liquid (serum) and they can easily break, making the patient feel uncomfortable. In some cases, the blisters have no identifiable cause and they heal without any treatment. However, when the blisters represent symptoms of underlying medical conditions, specific medical treatment is required. In case you cannot identify a clear cause that has led to the appearance of blisters on your hands, you should consult a doctor immediately.
In many situations, such as is the case of dyshidrotic eczema, the blisters on the hands are accompanied by blisters in other parts of the body, such as the feet, causing intense itchiness. Sometimes, the appearance of blisters on the hands is a sign of infection in the body or an allergic reaction of the immune system. The blisters can appear in acute, chronic or recurrent episodes; often times, the recurrence of the blisters is a sign that the underlying condition was not properly treated or that the infection is still present in the body. Also, it is important to determine whether the blisters are contagious or not. In many cases, they are not contagious but the patient is susceptible to infection because of the compromised tegument.
Causes of Blisters on Hands
These are the most common causes that lead to the appearance of blisters on hands:
Skin reaction to chemicals (this appears in patients who have a genetic predisposition and also an over-active immune system).
Chemical or thermal burns
The hand blisters resulting from burns are extremely painful and it is highly important not to break them, as this makes the affected area susceptible to infection and also leaves the patient dehydrated.
- Prolonged exposure to the sun, without adequate protection
- Patients with fair skin present a higher risk of developing blisters after prolonged exposure to the sun. This is why it is recommended to use high SPF sunblock, including on the hands.
- Viral infections
- Bacterial infections (staph bacteria are common)
- Intense and prolonged exposure to cold temperatures
- Immediate return to normal temperature should be avoided, as this can aggravate the condition and cause even more severe blisters to appear
Dyshidrotic eczema (Pompholyx)
- Blisters develop on the palms of the hands and soles of the feet
- Itchiness is present in the affected areas
- Allergies to chemicals or poisonous substances
- Poison oak and ivy
Physical irritation of the skin
- Friction or rubbing of the skin (including from tight gloves)
- Harmful irritation from different chemicals (cleaning products, cosmetics, skin care products)
- Extreme temperatures (extreme cold or heat)
Other skin conditions
- Dermatitis herpetiformis
Blistering skin conditions (inherited)
- Epidermolysis bullosa (blisters appear after trauma)
- Porphyria (blisters appear exposure to the sun)
- Nalidixic acid
- Severe cases: Erythema multiforme , Toxic epidermal necrolysis.
