Blisters on thighs are itchy

Herpes is a very common disease in our lives, and herpes will grow on the qualified parts of our skin, and the most common part is the thigh, because the skin in this part is particularly delicate, and the thigh is usually under the clothes, there may be more bacteria, which will cause herpes to spread in order to create a living environment. So what should I do if blisters grow on my thighs and they itch?

Causes of blisters

Blisters occur because the skin is damaged by some reason, such as abrasions, burns, scalds, etc. It is a protective response made by the body to protect the underlying skin from damage and ensure smooth regeneration of the skin. Generally speaking, during the regeneration process of the underlying skin, the fluid in the blisters will gradually be absorbed by the body, while the skin on the surface of the blisters will gradually dry, form scabs, and finally fall off. At this time, the lower layer of skin becomes the outer layer of skin. During this process, if the blisters burst, the inner layer of the skin is likely to be infected by bacteria, which may cause trouble for the child.

Differential diagnosis of blisters

(1) Impetigo: It often occurs around the nose and lips or exposed parts of the limbs. It is considered as herpes, which then turns into pustules and then scabs. It does not appear in batches, is not seen in mucous membranes, and has no systemic symptoms.

(ii) Papular urticaria: It is a spindle-shaped edematous red papule, the size of a peanut, with a needle-tip or millet-sized papulovesicle or blister in the center, which feels hard and very itchy. Distributed on the limbs or trunk, not involving the head or mouth, and no crusting.

(III) Herpes zoster: The herpes is distributed along a certain nerve trunk path, is asymmetrical, does not exceed the midline of the trunk, and has significant local burning pain.

(IV) Smallpox: Severe chickenpox is similar to mild smallpox.

(V) Other viral infections: Herpes simplex virus infection can also cause varicella-like skin lesions. This type of disseminated herpes simplex virus infection is often secondary to skin diseases such as atopic dermatitis or eczema, and the diagnosis depends on the results of virus isolation. In recent years, it has been found that enterovirus, especially Coxsackievirus group A, can cause widespread varicella-like rash, which usually occurs in late summer and early autumn when enterovirus is prevalent, and is often accompanied by lesions in the throat, palms, and soles of the feet. This helps to distinguish varicella from enterovirus infection.

(6) Chickenpox is a primary infection caused by the varicella-zoster virus. It is an acute infectious skin disease characterized by mild systemic symptoms and the appearance of macules, papules, blisters and scabs in batches on the skin and mucous membranes. It is more common in children, is highly contagious, and can easily cause epidemics in small areas. After recovery, the patient can obtain lifelong immunity.

Relieve itchy blisters

Don't think that the blister will be healed by puncturing it and letting the fluid inside flow out. On the contrary, you should try to keep the blisters intact, allow the liquid in the blisters to be absorbed by themselves, and allow the blister epidermis to dry, form scabs, and fall off on its own. If the blisters are caused by tight shoes or the child is wearing new shoes and the blisters are rubbed by the edges of the shoes, you should help the child protect the blisters with gauze pads on the affected area and let the child change into appropriate shoes and socks. If the blister is broken before the underlying skin has regenerated, the affected area should be cleaned, disinfected and bandaged with clean gauze immediately. If the blisters are caused by burns or scalds, or if the blisters are large, you should go to the hospital and ask a doctor for treatment. If the skin around the blisters becomes red and swollen or the blisters become purulent, it means that the skin at the blister site has been infected and you should go to the hospital for treatment immediately.

The above are all the details about the itchy blisters on the legs. If you develop similar blisters on your legs, you must find out the cause and never take any medicine at random. In addition, we often like to scratch blisters with our hands, which is wrong because our hands carry a lot of pathogenic bacteria. If you must scratch them with your hands, remember to wash your hands thoroughly, and it is best to disinfect them with alcohol before doing so.
