Sudden itchy fingers for unknown reason, what disease does it warn of?

The skin is not only a protective layer against physical impacts but also a sensory barrier. The skin continuously collects and transmits information from the surrounding environment to the brain, helping to sense temperature and pressure, according to the health website Medical News Today (UK).

Patients need to limit scratching itchy skin areas and identify allergens to prevent them.

Sometimes, the skin sends other signals to the brain, including the sensation of itching. The itching sensation is caused by stimuli on the skin. Nerves in the skin sense these stimuli and send signals to the brain.

When the finger itches, an uncomfortable feeling forms and the reaction is scratching. The intensity of the itch can vary, from mild to severe and persistent.

Causes of itchy finger skin

There are many causes of itchy fingers, ranging from physical to psychological factors. However, according to experts, one of the most common causes of itchy fingers is contact dermatitis. This condition occurs when the skin comes into contact with an allergen or skin irritant.

Contact dermatitis can occur anywhere on the body but is most common on the hands, face, lips and armpits. There are two main types of the disease: allergic contact dermatitis and irritant contact dermatitis.

Allergic contact dermatitis occurs when the immune system reacts to an allergen. Meanwhile, irritant contact dermatitis is caused by direct skin contact with a substance that can cause skin damage, such as a chemical.

Another cause of itchy fingers is dyshidrotic eczema. If you have this condition, you will develop small, clear blisters on your feet and hands that are itchy and painful. Stress, exposure to certain chemicals, allergens, or excessive sweating can cause or worsen the symptoms of dyshidrotic eczema.

Additionally, itchy fingers can be a symptom of a more serious health problem, such as psoriasis or nerve damage. These are both conditions that require medical treatment.

Besides physical causes, psychological problems such as stress, anxiety or emotional instability can also cause itchy fingers and hands.

How to treat

If your itchy fingers are caused by allergies or contact dermatitis, antihistamines can help reduce inflammation and control the itching. Your doctor may also prescribe a topical corticosteroid cream. If your itching is severe and is caused by eczema or psoriasis, your doctor may prescribe medications that target the underlying cause of the itching.

In addition, patients should limit scratching the itchy skin area. Identify allergens to avoid, according to Medical News Today.
