The pain after minimally invasive lumbar disc herniation may be related to nerve edema or recurrent condition, which needs timely review. If pain continues to occur after minimally invasive treatment of lumbar disc herniation, it is first considered to be caused by nerve edema, i.e., edema occurs in the nerves near the surgical site due to surgical stimulation, aseptic inflammation stimulation, etc., which in turn leads to abnormal nerve conduction function and pain manifestation. In addition, if the time gap is long, the possibility of recurrence of the disease cannot be ruled out, due to long-term improper sitting posture, poor rehabilitation, etc., resulting in lumbar disc herniation again, then recurring pain manifestations. At this time, you need to consult a doctor in time, under the guidance of the doctor to carry out nuclear magnetic examination, etc., to clarify the cause of the disease, and then follow the doctor’s instructions for treatment.
