Symptoms of spinal stenosis vary according to the area of stenosis, such as cervical discomfort, numbness in the upper limbs, thoracic and abdominal discomfort, lumbar and leg pain, and intermittent claudication. 1. Cervical spinal stenosis: patients may experience pain and discomfort in the neck, occiput, shoulder, back and other areas; limited cervical spine movement; radiating pain in one or both upper limbs; numbness in the upper limbs and so on. 2. Thoracic spinal stenosis: patients may have a feeling of binding in the chest and abdomen; stiffness, weakness, numbness and pain in one or both lower limbs, and even unsteady walking; in severe cases, urinary and fecal incontinence may occur. 3. Lumbar spinal stenosis: patients may have lumbago, sciatica, cauda equina syndrome (urinary and defecation disorders), intermittent claudication (walking for a period of time and then limping) and so on. Once any of the above symptoms appear, please go to the orthopedic department of the hospital in time.
