Soreness and swelling after minimally invasive lumbar spine surgery takes about 2 months, the exact time needs to be combined with the surgery and the patient’s physical condition. When minimally invasive surgery is performed on the lumbar spine, although the damage to the lumbar vertebrae and surrounding soft tissues is less than that of open conventional surgery, it is still traumatic for the organism. Minimally invasive lumbar spine surgery produces some slight damage to the local fascia, ligaments, muscles and other tissues, and even the vertebral body, which can lead to pathological changes such as hemorrhage, congestion, edema, and inflammatory reaction in the corresponding tissue structures, causing changes in local blood circulation, which results in a feeling of soreness and swelling. The complete elimination of such symptoms after surgery requires the disappearance of pathological reactions in the damaged tissues, which takes about 2 months, and the recovery time will be prolonged if the patient’s general health condition is poor and the underlying diseases are many. If there is any discomfort, it is recommended to consult a doctor in time.
