The treatment of postoperative leg pain in patients with lumbar disc herniation needs to be determined depending on the surgery, as follows: 1. The effect of radiofrequency and ozone treatment in minimally invasive surgery is slow, and some pain may remain after surgery, which needs to be recovered slowly; 2. For those who have leg pain after intervertebral foramoscopy technology, MED technology, and open surgery treatment, reasonable countermeasures need to be taken according to the cause of the disease: for those who have hematoma condition or bleeding after surgery, pain may be maintained If the pain is caused by irritation of the nerve root due to unremoved drainage tube, it is recommended to adjust the posture of the drainage tube or remove the drainage tube depending on the situation; if the leg pain is caused by residual surgical stent or re-projection of the stent, it is recommended to consult the surgeon promptly because the surgeon will make every effort to remove the disc and stent during surgery in such patients, but there is still a risk of re-dislodgement after surgery, and the incidence of the tube only is extremely low; For those who perform internal fixation surgery, postoperative leg pain needs to consider the position of internal fixation, infection factors, etc.
