Sudden blisters on your hands, still itchy? Doctor's advice: Or a sign of these diseases coming
The sudden appearance of small blisters on the hands, accompanied by an itchy sensation, can be uncomfortable and distressing. This may seem like a common symptom, but it can be a sign of certain diseases. Understanding these diseases is essential for early recognition and timely treatment.
Hand eczema. Hand eczema is an inflammatory reaction to the skin of the hands caused by exposure to various external irritants, and it is generally difficult to determine the cause. Most of them have a slow onset and high incidence, and the clinical manifestations are dry hands, dark erythema, local infiltration and hypertrophy, and often dehiscence in winter.
It is a common skin condition that manifests as redness, itching, and the appearance of small blisters. The causes of eczema are varied, including genetics, environmental factors, contact irritants or allergens, etc. Treatment of hand eczema usually involves avoiding known irritants and allergens, using humectants to keep the skin moisturized, and using topical corticosteroids or other medications under the guidance of a doctor.
Dyshidrosis, also known as dyshidrosis, is a skin condition associated with excessive sweating. Dyshidrosis is a type of skin eczema, a blistering skin disease that can occur on the palms and soles. Because it occurs in the hands and feet, where sweat glands are particularly developed, and blisters are the main manifestations, it was once thought to be related to sweating glands, and it was named sweat herpes.
It usually occurs on the palms and soles of the feet and manifests as bursts of small blisters that may cause intense itching. Treatment of dyshidrosis may include the use of astringents to reduce sweating and topical corticosteroids to reduce inflammation and itching.
Herpes zoster is an acute infectious skin disease caused by the varicella-zoster virus. Some people become infected and become carriers without developing symptoms. Because the virus is neurophilic, it can be latent in the neurons of the posterior root ganglia of the spinal cord nerve for a long time after infection, and when the resistance is low or tired, infected, or cold, the virus can grow and multiply again and move along the nerve fibers to the skin, causing strong inflammation of the invaded nerve and skin.
Contact dermatitis is an inflammatory reaction that occurs at or beyond the site of contact after single or multiple exposures of the skin or mucous membranes to a foreign substance. Presents with erythema, swelling, papules, blisters, and even bullae.
In addition, this can cause redness, itching, and small blisters on the skin. Common irritants include detergents, soaps, chemicals, and certain plants. The key to treating contact dermatitis is to identify and avoid irritants or allergens, and topical corticosteroids may be needed to reduce inflammation.
Certain infectious diseases, such as chickenpox and hand, foot and mouth disease, can also cause small blisters on the hands. Chickenpox (varicella, chickenpox) is an acute infectious disease caused by primary infection with the varicella-zoster virus. It occurs mainly in infants and preschoolers, and the symptoms are more severe in adults than in children.
It is mainly characterized by fever and the appearance of erythematous maculopapular rash, herpes, and crust rash in batches on the skin and mucous membranes, and the rash is centripetally distributed, mainly on the chest, abdomen, and back, and rarely on the limbs. Hand, foot and mouth disease (HFMD) is a viral disease that affects infants and young children. These infections usually take time to heal on their own, and it is important to practice good personal hygiene and avoid close contact with sick people to prevent transmission.
The sudden appearance of small blisters and itching on the hands should not be ignored. While many conditions may be mild and temporary, they can also be a harbinger of a more serious illness. It is crucial to recognize these symptoms and seek medical advice promptly. Proper care and treatment can effectively alleviate symptoms and prevent the disease from progressing further. It is important to remember that early diagnosis and treatment are key factors in maintaining good health.
