The weather is hot, and there are many blisters on my fingers, which are not itchy, like sweat can't be discharged. What should I do?

The most common situation is herpes zoster, which is a skin eczema reaction caused by local sweating. It is characterized by dense needle-like thick-walled blisters under the skin of the hand, accompanied by severe itching. Generally, it is easy to be allergic, and people who sweat more are easy to get it. For treatment, glucocorticoid ointment such as halometasone ointment and mometasone furoate ointment can be used externally, and oral antiallergic drugs such as loratadine tablets and cetirizine tablets can be used. Severe cases can also be treated with oral prednisone tablets. Usually avoid emotional tension, avoid overheating and sweating too much, and don't eat spicy food.
