Surgery is not always necessary for lumbar spinal stenosis, and in previous clinical experience, only about 1/3-1/4 of patients with lumbar spinal stenosis required surgery. There is a specific description of which patients do not need surgery and which patients do. In terms of symptoms, if the patient’s symptoms have seriously affected daily life, resulting in a very low quality of daily life for the patient, such as walking, only 10-20 steps, and unbearable pain in the back and legs, which is still not relieved by non-surgical treatment in the early stage and is currently causing relatively great pain to the patient, then surgery is recommended. If the patient’s symptoms have not reached a condition that seriously affects daily life, and the patient can tolerate the back and leg pain and numbness, or has not yet undergone non-surgical treatment, surgery is not recommended, and conservative treatment can be carried out first, such as small weight traction of the lumbar spine, acupuncture, massage, sacral canal injection, and various kinds of physical therapy and hot compresses, all of which can achieve the purpose of treatment.
