Spinal stenosis can be treated by the following methods: 1. If the spinal stenosis is not serious and the symptoms are not obvious, it can be treated by conservative treatment, commonly used methods include blood circulation, circulation improvement, tendon relaxation, nerve nutrition, anti-inflammatory and pain relief, most of which can be relieved or cured by the above treatments. 2. If the above treatment is still not effective, it is time to take pictures to determine the severity and decide that surgery may be needed, including spinal decompression, nerve root release and internal fixation with bone grafting.
