After cervical radiofrequency ablation may cause recurrence of cervical spondylosis, pain at the puncture site and abnormal sensation. 1. It may cause recurrence of cervical spondylosis: It may cause disc herniation and ligament thickening due to improper exercise of the cervical spine without following the doctor’s instructions, resulting in recurrence of cervical spondylosis. 2. It may cause pain at the puncture site: it may cause pain at the puncture site because the practical puncture needle is thicker and the patient’s puncture site is more sensitive, but it is relatively rare. 3. It may cause abnormal sensation: It may cause numbness, coldness and other abnormal sensation in the neck, shoulder or other parts of the upper limbs due to some nerve stimulation. The abnormal sensation may persist for a long time, but it has no effect on other sensations. Please go to the relevant specialized hospitals in time if you have the above symptoms.
