The causes of sciatica are complex, and the common one is lumbar disc herniation. Since sciatica is not a single disease, but a symptom that occurs in many diseases. In clinical practice, sciatica is more often described as a symptom of lumbar spine diseases (such as lumbar disc herniation and lumbar spinal stenosis).
What are the symptoms of sciatica?

Five ways to prevent sciatica?
1. Prevent the wind from lasting too long, in the hot weather in summer, under the fan or in a cool and ventilated place after sweating, in the case of exposed shoulders, blowing for too long, can easily lead to sciatica.

2. Cold protection, if wind, cold, and dampness invade the lower back of the human body, the lumbar disc and surrounding soft tissues may be inflammatory and stimulated and cause fibrous rings to break, inducing lumbar disc herniation, lumbar spinal stenosis and other diseases, and then compressing the nerves and inducing sciatica. Therefore, in the cold winter and humid season, you must pay attention to cold protection and warmth, and never ask for demeanor or temperature.

3. Prevent fatigue, sciatica generally worsens when you are tired, so you must avoid overwork. For sedentary office workers, in addition to the correct sitting posture, it is also necessary to move the waist appropriately to avoid maintaining the same posture for a long time. For some manual workers, it is necessary to avoid overwork and correct wrong postures, such as bending over with straight legs to pick up objects; If necessary, some labor protection measures should be taken, such as waist and knee protection.

4. Avoid trauma, in daily life, you should be careful to avoid trauma. If trauma is sustained, it should be treated immediately. 5. Prevent or delay the occurrence of degeneration, clinical studies have shown that the incidence of sciatica is related to stillness, old age, injury and cold. Quiet, the finger moves less. Old age, referring to degeneration, is the main internal cause of the disease. Therefore, to prevent the occurrence of this disease, it is necessary to insist on physical exercise from a young age to prevent or delay the occurrence of degenerative degeneration.
