Symptoms after radiofrequency surgery for cervical spine herniation may be caused by the postoperative recovery period, incomplete resection of herniated discs, or lesions in neighboring segments. 1. Postoperative recovery period: general discomfort symptoms can be relieved after radiofrequency surgery for herniated cervical vertebrae, but in the short term, it is still not possible to completely and thoroughly improve the symptoms, and there will still be some pain in the neck or upper limbs, numbness of the limbs, etc. This situation is mainly in the postoperative recovery period. This situation is mainly in the postoperative recovery period, with the postoperative recovery, the symptoms can gradually disappear. 2. Incomplete removal of herniated disc: Radiofrequency ablation of cervical disc herniation is a minimally invasive surgery. Although the surgery can deal with herniated discs, it cannot remove the herniated discs fundamentally due to the limited scope of the treatment, so there are still some postoperative symptoms. 3. Neighboring segment lesions: Cervical disc herniation may be the result of a combination of lesions in two or more segments. Therefore, if radiofrequency ablation is performed to treat the segment with severe lesions, the symptoms can be improved in the short term after the surgery, but the aggravation of the lesions in the neighboring segments will cause the symptoms of neck discomfort to persist.
