Why Do I Have Painful Blisters on My Body without Itching?

Some people develop blisters on their bodies. These blisters are not itchy but rather painful. It is important to take this phenomenon seriously as it could be caused by herpes. Herpes is divided into two categories: simplex herpes and zoster herpes. Zoster herpes is a skin disease caused by varicella virus infection and is contagious, especially among individuals with low immunity. The most typical symptom of zoster herpes is neuropathic pain. Let's delve into the issue of why blisters that are not itchy but painful may appear on the body.

Why Do Blisters Appear on the Body That Are Not Itchy but Painful?

The development of transparent and painful blisters on the body is likely caused by herpes. Herpes is generally categorized into two types: zoster herpes and simplex herpes. Both types manifest as blisters forming on a base of erythema. Early blisters are transparent and accompanied by a certain degree of pain. The infectious agent of simplex herpes is herpes simplex virus, which is generally classified into type 1 and type 2. Type 1 herpes is usually distributed around the mouth, nose, and eyes, while type 2 herpes is typically found on the genitals and anus, hence it is also known as genital herpes. Zoster herpes can occur in any part of the body and is distributed in a zoster-like pattern.

How to Manage Herpes?

The incidence of herpes is particularly high, and many individuals experience multiple herpes lesions accompanied by itching and pain. This not only compromises their physical health but also affects their daily lives and work. It is important to be vigilant against the emergence of herpes and to prioritize general treatment measures upon onset. During the illness, patients should rest adequately, consume easy-to-digest foods, and maintain adequate water intake. Additionally, antiviral treatment is necessary, with nucleoside drugs being the most effective agents against HSV. These include oral medications such as valaciclovir, aciclovir, and famciclovir. Topical applications like aciclovir cream or penciclovir cream can be used on affected skin areas to effectively alleviate symptoms. It is also essential to address symptoms specifically. For patients with unbroken skin lesions accompanied by itching, calamine lotion can be applied. Once the herpes blisters rupture, patients should apply antibiotic ointments. Many patients with zoster herpes experience pain, and analgesics such as indomethacin may be prescribed. Oral or intramuscular administration of vitamins B1 or B12 may also be recommended. In cases of secondary infection, topical applications like neomycin cream or mupirocin ointment should be used. Patients should also maintain good hygiene.
