The blisters on my hands are itchy, and the more I scratch them, the more itchy they are. It has been several years. Winter is better and summer is the worst. What can be done to cure them? What is the reason? There are blisters and itching on the hands, usually tinea manus. Tinea manus, commonly known as Liriodendron, is caused by fungal infection. According to the shape of rash, it can be divided into three types: blister type, scale type and erosion type. Patients often feel itchy at first, and the skin on their hands will appear papules, erythema, desquamation and blisters, which we call "small blisters". At first, it was a small part. With the passage of time, the damage gradually expanded and the boundaries were clear. After a long time, hand skin will become rough, dry and thick. It can also be accompanied by chapping and bleeding.

The occurrence of tinea manus mostly comes from scratching tinea pedis. Partly because some airtight clothes will increase the local temperature and humidity of the skin and interfere with the barrier function of the stratum corneum. Whether tinea manuum or tinea pedis, if left unchecked, almost all patients will eventually develop toenail infection, forming onychomycosis or onychomycosis, which is more stubborn than tinea manuum and tinea pedis.

Therefore, tinea manus and pedis must not be underestimated in daily life, which will lead to more serious ills and should be actively treated. At present, there are many drugs for treating tinea manus and pedis, which are divided into two categories: external drugs and oral systemic drugs. Oral therapy is often only used for cases with large skin lesions, stubborn skin lesions and difficult external use, but it should be used under the guidance of a doctor.
