Whether or not sciatica will heal on its own requires a judgment of the cause, and common causes include lumbar disc herniation, pyriformis syndrome, and lumbar spinal stenosis. 1. Lumbar intervertebral disc herniation is mostly caused by sedentary factors, resulting in lumbar nucleus pulposus protruding from the spinal canal and compressing the local spinal cord, which can cause sciatica symptoms, and this condition cannot be cured by itself. 2. Piriformis syndrome is mostly caused by trauma or excessive exercise, resulting in local muscle congestion and edema, combined with inflammatory infiltration, which can compress or stimulate the sciatic nerve, resulting in symptoms of sciatica, which usually takes 1 week to heal itself. 3. Lumbar spinal stenosis is mostly caused by congenital growth and developmental abnormalities or trauma and other factors, resulting in a reduction in the volume of the local spinal canal, stimulation or compression of the local spinal cord, which can cause sciatica symptoms, and this situation can not be self-healing. If symptoms of sciatica appear, you should be vigilant and consult a doctor in time to find out the cause of the disease, so as to avoid delaying the condition. In your daily life, you should avoid trauma and excessive exercise, and combine work and rest.
