Shingles is a common dermatological disease primarily caused by the varicella-zoster virus. Shingles has an incubation period, but the duration is uncertain, generally ranging from 3 to 20 days. The reason the incubation period for shingles is variable is that after being infected with the varicella-zoster virus, it accumulates in the nerves of the spinal cord and does not exhibit any symptoms physiologically. The virus only begins to proliferate rapidly and triggers the disease when the body's resistance decreases, or in the event of an infection, a cold, or fatigue.

Shingles is what disease?

Shingles is primarily caused by the varicella-zoster virus, which enters the human bloodstream through the respiratory tract mucosa, leading to chickenpox or a latent infection. The virus then lies dormant in the nerve ganglia of the body. Certain triggers, such as trauma, fatigue, weakness after illness, malignant tumors, or the use of immunosuppressants, can decrease the body's resistance and activate the dormant virus, resulting in shingles.

Does shingles leave scars?

After shingles heal, in most cases, there are no scars left. Shingles typically cause symptoms such as blisters or rashes on the skin, which are mostly located in the epidermal layer of the skin and do not infect below the dermis. Therefore, once these blisters heal, they only scab over on the epidermal layer. After the scab falls off, the original skin regrows without any scarring. However, if the patient is prone to scarring, they are generally left with scars.

Clinical manifestations of herpes zoster

Shingles is a disease caused by the varicella-zoster virus infection. Its most characteristic symptom is the appearance of clustered small blisters distributed along nerve paths on one side of the body, which are quite painful and generally do not cross the midline. This disease has a certain natural course, and it can usually heal within one week to ten days. Some individuals, if in good physical condition and with strong immunity, may recover without medication. However, once identified, it is best to treat with antiviral medications. Delaying treatment may lead to postherpetic neuralgia, which involves severe pain. Therefore, it is crucial to undergo proper treatment once the disease is detected. During treatment, patients should rest more, drink plenty of water, and avoid spicy and irritating foods.

What family does shingles belong to?

Shingles can be treated in three medical departments. First, dermatology. Since the blisters primarily appear on the skin, seeing a dermatologist can treat shingles. Second, neurology. As shingles may be caused by nerve damage, treatment can be sought from a neurologist. Third, for severe pain, especially if postherpetic neuralgia remains after shingles, one can consult the pain management department. The initial symptoms of shingles are mainly pain, particularly unilateral limb or unilateral scalp/facial pain.

herpes zoster symptoms

The symptoms of herpes zoster primarily manifest as irregular erythema on certain parts of the body's skin, followed by clusters of rice-grain or mung bean-sized raised vesicular rash, blisters, and blood blisters. These rashes generally appear on one side of the body, not crossing the body's midline, and are accompanied by local sensations of burning, scalding pain, stabbing pain, numbness, itching, and other abnormal neural sensations.
