Why old blisters? What should I do if I keep getting blisters on my hands?

Is it athlete's foot, don't delay too long, go to the doctor.

There are always blisters on the hands, and the following diseases are considered:

1. Dyshidrosis, which usually occurs in the heart of both hands, appears transparent deep blisters. In clinical practice, fexofenadine hydrochloride tablets or desloratadine capsules can be taken orally, mometasone furoate ointment can be applied externally, mixed with dimethicone ointment. After applying, you can also wet compress compound cork liquid coating to achieve the best effect of dampness and detoxification.

2. Bullous pemphigoid, which is caused by the appearance of immune antibodies that destroy its own tissues in the basal layer, can be carried out by oral administration of niacinamide tablets, minocycline hydrochloride capsules and glucocorticoid drugs, such as triamcinolone tablets, prednisone acetate tablets, topical halomethasone ointment, fluticasone propionate ointment and other medium-potent and powerful glucocorticoid drugs.

Dyshidrosis herpes, also known as dyshidrosis eczema, is a blistering disease that occurs on the palms or soles of the feet. Dyshidrosis is mainly manifested as small blisters deep in the **, which are densely distributed and may be accompanied by itching and burning.

The blisters can be absorbed naturally and slowly, and after drying up, they peel off, and there is ** dryness and discomfort. In general, dyshi herpes is milder and can heal on its own. If it persists, you may need to go to the hospital for symptomatic treatment according to the doctor's instructions.

The blistering stage is mainly dry and plucked, and calamine menthol lotion or traditional Chinese medicine can be used to wash externally, and some ointments or moisturizing creams can be applied after peeling.

In fact, it is very simple that the immunity is declining, the immunity is low, and why the immunity is declining is usually due to several reasons.

The first is that after exertion, the body resistance decreases after staying up late or stressed, which causes herpes virus infection, which is the ** of many young people, who are very tired after staying up late or on a business trip, and it is easy to get shingles at this time.

The second is the elderly, the elderly themselves are older, the body's resistance itself is reduced, if it is not good to rest at night, poor sleep or stress, it will also cause shingles.

The third is that after getting cold, especially when the season changes, the weather suddenly becomes cooler, if you don't pay attention to keeping warm, people's immunity is also low, and it is easy to be infected with long shingles, so every time the season changes, the number of shingles patients will suddenly increase.

The fourth situation is that the body is combined with other diseases, such as lymphoma or HIV infection or some pneumonia or more serious diseases, the body's immunity is poor, at this time, if you are exposed to the virus or have had chickenpox before, the virus itself exists in the body, and the virus will activate and cause symptoms.

If you have shingles, you need to analyze the cause, try to find the cause of the weakened immunity, and you also need to do some tests to rule out some diseases, so you can do the usual routine examination, but if you are young or have high-risk sexual contacts, you still need to check for HIV.

Many people may not have found it before, and after getting the herpes virus, they will check that HIV is positive, so after getting herpes, on the one hand, it is ** on the one hand, it is to check, try to find the cause, and on the other hand, pay attention to rest and restore the body's resistance as soon as possible.

The occurrence of herpes simplex is mainly due to direct contact with the infected person or mucous membrane, and the herpes simplex virus invades the body through the mucosal lesion, and the primary infection occurs. Most of them are occult infection, about 10% of them have symptoms, and the virus is latent in the local sensory ganglia after ** or natural remission, so that the host is infected. Under certain conditions, such as fever, cold, fatigue, nervousness, menstruation, etc., the herpes simplex virus is activated and replicates, causing a rash in the distribution area of the affected nerves**, and viremia can be formed when the body's immune function is low, and systemic disseminated **infection occurs.

Herpes simplex is a disease caused by herpes simplex virus, which is good to invade the mucosal junction, herpes simplex is manifested as localized cluster vesicles, herpes simplex is called "hot sores" in Chinese medicine, and it is more common in **rash: at the junction with the mucosa, especially at the corners of the mouth, lip edge, nostrils, etc., it is characterized by clusters of small blisters on the basis of erythema, mostly in clusters; The blister fluid is first transparent and then turbid, and after it is scratched, it erodes, moisturizes, and crusts, and can also be secondary infection. The course of the disease is about 1-2 weeks, and it can still be in place after healing**.

Herpes zoster is an acute viral disease caused by herpes virus, dense vesicles and neuralgia distributed along one side of the peripheral nerve, and regional lymphoma. Herpes symptoms, imitation herpes zoster first has 1-5 days of localized ** stinging, and then on the face or chest, back and waist and abdomen appear multiple clusters of small blisters, the distribution of which is limited to one side of the body, arranged in bands, the pain is often intense. After a week, the blisters begin to dry up and scab over, and then the scabs come out and heal, usually taking 2-3 weeks.

Older people may have posterior neuralgia. After healing, there can be permanent immunity, so it is no longer **.

1. Acantholysis: due to the epidermal intercellular bridges (desmosomes and tension filaments, etc.), the cells lose their close connection and become a state of release, thus forming fissures, sores or large hugs in the epidermis. Acantholysis is caused by autoimmune causes, such as pemphigus.

Acantholysis caused by genetic causes is seen in chronic familial benign natural cancer sores and follicular keratoses.

2. Basal cell liquefaction and basement membrane lesions: basal cell liquefaction refers to the vacuolization or fragmentation of epidermal basal cells, the disappearance of the basal cell layer in severe cases, and the direct contact between spinous cells and the dermis, and immune, genetic and drug allergies are often the reasons for basal cell liquefaction, which can be seen in hereditary epidermolysis macrocarcinomatosis, systemic lupus erythematosus, dermatomyositis, erythema multiforme, drug eruption, and lichen planus. Basement membrane lesions refer to autoantibody deposition or congenital pathological defects in the basement membrane, due to autoimmunity and genetics, and watery dysentery caused by basement membrane lesions include macrocarcinous pemphigoid, herpes graviformis, protoscarial pemphigoid, dermatitis herpetiformis, linear K-human disease, acquired carcinomatous epidermolysis, congenital serious epidermolysis, and pigmentary incontinence.

3. Balloons and reticulums: due to intracellular edema, the volume of epidermal cells increases, forming a balloon, the cells swell and rupture, and the adjacent residual cell membranes are connected to form most of the reticular septum, and finally multilocularis is formed, which is more common in viral infectious diseases.

4. Herpes zoster**: It is caused by filtration virus, trauma, syphilis, spinal cord disease, arsenic poisoning.
