How is snake-like waist pain caused?

　　Snake-like waist, commonly refers to herpes zoster. Generally, the main causes of herpes zoster include the latent activation of varicella-zoster virus, decreased immunity, excessive fatigue, colds and fever, diabetes, etc. If discomfort symptoms occur, it is recommended to seek timely treatment at a regular hospital. Detailed analysis is as follows:

　　1. Latent activation of varicella-zoster virus

　　After the first infection with varicella-zoster virus in the human body, the virus remains dormant in the sensory ganglia. When the body's condition changes, the virus gets activated and spreads along the nerve fibers, causing herpes zoster. Antiviral medications such as acyclovir tablets, valacyclovir tablets, and famciclovir tablets should be used under a doctor's guidance to inhibit viral replication. Additionally, keep the skin clean and avoid scratching the affected area to prevent infection.

　　2. Decreased immunity

　　Long-term mental stress and unbalanced nutrition can lead to reduced immunity, which prevents suppression of the dormant varicella-zoster virus, allowing the virus to multiply easily and cause disease. In daily life, maintain a regular routine, avoid staying up late, consume more protein- and vitamin-rich foods such as eggs and vegetables, and engage in moderate exercise like jogging or yoga to enhance immunity.

　　3. Excessive fatigue

　　Prolonged high-intensity work or frequent physical labor in an overworked state can damage bodily functions, reduce resistance to viruses, and trigger herpes zoster. Arrange work and rest reasonably, avoid prolonged continuous labor, rest promptly when tired, and relieve physical fatigue through methods such as taking hot baths or massage.

　　4. Colds and fever

　　During a cold or fever, the body is in a state of stress, and immune system function is affected, making it easier for the dormant varicella-zoster virus to become active. Drink more warm water to promote metabolism, keep warm to avoid catching a chill, and when body temperature exceeds 38.5°C, use medications such as paracetamol tablets or ibuprofen sustained-release capsules under a doctor's guidance for fever reduction. Follow medical advice to use cold medications to alleviate symptoms.

　　5. Diabetes

　　Diabetic patients with long-term poor blood sugar control may suffer damage to the immune system and nerve tissues, increasing the likelihood of varicella-zoster virus activation. Moreover, symptoms may be more severe after infection. Strictly follow medical advice to take hypoglycemic drugs such as metformin hydrochloride tablets, glimepiride tablets, or use insulin injection to control blood sugar. Regularly monitor blood glucose levels to maintain stable blood sugar control.

　　In daily life, maintain a positive mindset and avoid excessive mental stress; pay attention to personal hygiene and change clothes frequently; eat a balanced diet, reducing intake of high-sugar and high-fat foods; and undergo regular health check-ups to promptly detect and manage underlying diseases.
