There are small transparent blisters on the surface of the left finger, which are not very itchy, and basically have no feeling. It just looks very uncomfortable, especially on the two sides of the finger belly near the nail. Sometimes there are patches on both sides of the second finger joint and the outside of the thumb. It will disappear after a few days without squeezing. I'd like to explain the reasons for this situation.

What reason does left hand finger itch blister

Reason 1: sweat herpes easily appears on hands in summer, which is a kind of eczema. The main symptom is blistering, sometimes itching, some peeling, some not peeling. Sweat herpes tends to heal itself. It occurs in spring and summer, and nodules disappear in autumn and winter.

The second reason: allergy. However, compared with other common allergies, this kind of allergy should be relatively rare. However, once you leave the allergen, your condition will improve, and even recover by yourself. Therefore, it is up to the patients to pay attention to their own allergens.

Reason 3: the occurrence of blisters is a protective reaction made by the body in order to protect the lower skin from injury and ensure the smooth regeneration of the skin because the skin is injured for some reason, such as abrasion, burn, scald and so on. It is suggested that you can take vitamin B or vitamin E orally, which can effectively enhance the skin resistance.
