The absence of pain and only itching in patients with shingles may be an early symptom of the disease or it may be related to the patient’s body type.
Shingles is a disease caused by the reactivation of the varicella-zoster virus in the patient’s body. The patient’s initial infection with the virus usually results in chickenpox; after healing, the virus lurks in the body’s nerve ganglia, and when immunity is low, the virus is reactivated and proliferates along the invaded nerves, resulting in symptoms such as nerve involvement and blisters along the nerve-distributed skin.
Typical symptoms of herpes zoster are clusters of painful blisters distributed in bands. In the early stage of the disease, the patient’s inflammatory damage to the affected nerves is not serious, and symptoms such as itching, numbness, ants and burning may occur, but with the progression of the disease, symptoms of localized pain may appear.
At the same time, clinically, some patients have a high threshold for pain, i.e., they are not sensitive to pain, so they do not experience pain, but symptoms such as numbness, itching, pins and needles, ants and ants, burning, and tenderness are all symptoms of nerve involvement. Therefore, not all patients with shingles will experience symptoms of pain.
It is recommended that patients with herpes zoster go to regular hospitals in time to seek medical treatment, and standardize antiviral, pain relief, and nerve nutrition treatments under the guidance of doctors.
