Lumbar spinal stenosis may generally compress the sciatic nerve, cauda equina, etc., and pain can occur in these areas. Lumbar spinal stenosis is caused by congenital hypoplasia of the spinal canal, trauma, inflammation, and other factors that lead to lumbar spinal stenosis. Generally, if a patient with lumbar spinal stenosis has mild symptoms, there is often no obvious discomfort. However, with the development of the disease, lumbar spinal stenosis can compress the sciatic nerve, resulting in sciatica, which can spread to the lower extremities, radiating to the buttocks and the back of the foot. Lumbar spinal stenosis can also compress the cauda equina nerve, resulting in perineal numbness, abnormal sensation in the saddle area, and some patients may experience urinary and defecation disorders, sexual dysfunction and other conditions. Typical symptoms of lumbar spinal stenosis include low back pain, which can occur on one side or both sides and worsens when standing or walking. Once the above symptoms appear, it is recommended to go to a regular hospital to clarify the cause of the disease. Meanwhile, relevant treatment measures need to be taken under the guidance of a doctor to avoid delaying the condition.
