Spinal stenosis does not heal on its own and requires surgical treatment in order to be cured. Spinal stenosis is mainly due to the possibility of spinal cord edema when the spinal cord is compressed by the narrowing of the spinal canal. Therefore, the medication mainly reduces the edema of the spinal cord in the spinal canal, and the symptoms may be relieved when the spinal cord becomes slightly smaller. However, the self-causes of spinal stenosis, including ligamentous hypertrophy, disc herniation, and osteophytes, cannot heal themselves. If symptoms are not relieved after treatment with medication to eliminate spinal cord edema, surgery is the only way. For spinal stenosis in the cervical and lumbar spine is treated by surgery to remove excessive hyperplastic bone and localized hyperplastic calcified ligaments, relieving the localized intervertebral disc bands from compression, and bringing relief to the symptoms. When these factors are lifted, the localized nerves are restored. There are also many current treatments available, and minimally invasive treatments are now available for patients who are particularly old and cannot tolerate major surgery. However, the long-term efficacy of minimally invasive treatment for spinal stenosis is not certain. For severe cases prompt treatment is needed to prevent nerve damage. Lumbar and cervical spinal stenosis require functional exercises after surgery, to exercise the muscles of the neck and lumbar region, to prevent atrophy and weakness of the muscles, and to strengthen the muscles to maintain the stability of the joints.
