A tingling sensation in the skin.

When the skin feels a needle-like tingling sensation, be alert for the onset of herpes zoster, which is caused by varicella zoster virus infection. Many patients first show needle-like skin pain, such as low back pain, chest pain, etc., before the rash manifests itself. It is often misdiagnosed as other internal diseases, such as appendicitis, biliary colic, etc. After normal pain lasts for several days, clusters of blisters appear on the skin and are distributed along the nerve path. The treatment of herpes zoster is mainly based on antiviral drugs, which can improve symptoms and shorten the course of disease.
