Spinal stenosis does not heal on its own. If left untreated, the condition will get worse. Spinal stenosis includes cervical spinal stenosis, thoracic spinal stenosis, and lumbar spinal stenosis, which have different effects. In the case of cervical spinal stenosis, it can cause numbness of the limbs, neck pain, and also affect limb movement and urinary and fecal dysfunction, and in severe cases, paraplegia and fecal incontinence can occur under the influence of minor external forces. In the case of thoracic spinal stenosis, it may cause pain in the patient’s back, which is difficult to be relieved, and may lead to numbness and weakness in the lower limbs, unstable walking, and limping. In case of lumbar spinal stenosis, it may also produce numbness and pain in the lower extremities, abnormal function of urination and defecation, etc. Patients may experience intermittent claudication when walking, which is relieved after standing or squatting and resting. All three conditions are difficult to heal on their own and require active treatment and, if necessary, surgery to relieve compression in order to avoid disease progression. In daily life and work, patients should pay attention to avoid maintaining the same position for a long time, strengthen the back muscle exercise, and do sports appropriately.
