What causes blisters on wrists

If blisters appear on the wrist, it may be due to herpes simplex, a viral infection that is quite harmful to human health. It should be treated with medication in time. Some external medications can achieve a good therapeutic effect. If a serious systemic infection occurs, internal medications should be used for treatment. During the treatment process, diet adjustment and good rest are very important.

What causes wrist blisters?

Herpes simplex. It may be related to viral infection. 1. Local treatment: topical antiviral drugs such as acyclovir ointment, herpes eye drops, phthalamide lotion, etc. Or apply 20g of 40% zinc oxide oil plus 0.25g of chloramphenicol injection topically several times a day. If secondary bacterial infection occurs, erythromycin or chloramphenicol ointment can be applied externally, or norfloxacin and Bactroban ointment can be used.

2. For systemic treatment of severe infection, the antiviral drug acyclovir can be taken orally, with the same dosage as for herpes zoster. For patients with secondary severe bacterial infection, antibiotics should be used as appropriate. For cases with recurrent attacks, oral zinc preparations such as zinc gluconate can be used in combination with external wet compresses using 0.05% zinc sulfate solution. Immunomodulators such as levamisole and transfer factor can also be injected subcutaneously.

What is Herpes Simplex

Human HSV is a DNA virus, which is divided into two subtypes according to its antigenic properties: HSV-I and HSV-II. HSV-Ⅰ mainly invades the face, brain and areas above the waist, while HSV-Ⅱ mainly invades the genitals and areas below the waist. Normal people can be virus carriers.

Humans are the only natural host of the herpes simplex virus, and 70% to 90% of adults have been infected with HSV-Ⅰ. The virus enters the body through the mouth, respiratory tract, genitals and broken skin, and resides in the normal mucous membranes, blood, saliva, nerve tissue and most organs. When certain predisposing factors such as fever, cold, sun exposure, emotional excitement, gastrointestinal dysfunction, drug allergy, excessive fatigue, mechanical stimulation, menstruation, pregnancy, etc. contribute to the occurrence of this disease, it can spread through the blood or neural pathways.

Differential Diagnosis

It is not difficult to diagnose patients with typical herpes lesions on the body surface. Common herpes simplex is mostly recurrent, and the diagnosis can be made based on the clinical characteristics of the skin lesions and the site of the outbreak. Misdiagnosis may occur in patients with some rare primary infections, or when lesions only exist deep in the cavity (such as the reproductive tract, respiratory tract, etc.), or when there are only visceral herpes lesions but no lesions on the body surface. This disease sometimes needs to be differentiated from facial herpes zoster, impetigo and fixed drug eruption.
