Leg and foot pain after spinal embolism surgery is mainly caused by the separation, pulling and even electrical stimulation of peripheral nerves during the surgery, which is within the normal range. Spinal embolism is caused by the abnormal state of the spinal cord, such as end-filament tension, intravertebral lipoma, etc. During the surgery, the surgical site is separated layer by layer, and during the process of separating the end-filaments, the peripheral nerves are separated, pulled, and electrophysiology and electrical stimulation are applied to the end-filaments in the surgical process, all of which will cause sensory abnormality, and leg and foot pain will occur. In the process of spinal cord ascension and displacement, the peripheral nerves are also pulled, causing abnormal sensation in the lower limbs and leg and foot pain, which is mostly transient and reversible. Leg and foot pain caused by spinal cord embolization surgery is mostly temporary, and should be followed up regularly after the surgery. If the symptoms worsen again, you should go to the hospital as soon as possible.
