Herpes zoster occurs when the virus latent in the ganglia reactivates due to various factors that lead to a weakened immune system.

The typical symptom is initially the absence of a rash, accompanied by pain, itching, or discomfort, followed by the appearance of distinct blisters with pain or itching, primarily characterized by pain, indicating a viral skin condition. This type of herpes, particularly in older individuals or those with compromised immunity, often presents with numerous blisters from the onset and severe pain, suggesting significant neural inflammation, which may increase the likelihood of developing postherpetic neuralgia in the future.

Although shingles can resolve on its own without treatment, the nerve damage and inflammatory response caused by the virus may lead to prolonged neuralgia in some individuals. Therefore, it is essential to promptly initiate oral antiviral medications within 72 hours of the onset of shingles, such as acyclovir, valacyclovir, famciclovir, or brivudine. Additionally, nerve-nourishing supplements like vitamin B1 and mecobalamin, pain relievers, and topical medications should be considered. Of course, this represents the Western medical approach. Traditional Chinese Medicine may incorporate its own distinctive methods on this basis, including acupuncture and other therapies, which can also be explored.

Some individuals may indeed experience severe cases of shingles, even developing disseminated herpes zoster, which can be slightly more contagious and may require intravenous treatment. In such cases, it is essential to seek medical care at a hospital.

For mild shingles, additional medication can be considered, but some drugs are prescription-only, which can be more complicated. At the same time, ensure you have knowledge about shingles and confirm you have no drug allergies to avoid adverse reactions.

Finally, it is not necessarily mandatory to go to the hospital for herpes zoster. As mentioned earlier, the prerequisite for not seeking hospital care is a clear diagnosis of herpes zoster, along with timely pharmacological treatment to reduce the occurrence of postherpetic neuralgia.

Are folk remedies effective? Personally, I do not recommend them, as it is essential to undergo formal antiviral treatment for diseases that are clearly caused by viral infections.
