The symptoms of post-surgical swelling and numbness after spinal cord surgery depend on the patient’s location and spinal cord injury. Generally speaking, the symptoms of neurogenic edema gradually disappear in about 2 weeks, and the preoperative swelling and numbness of the limbs take 3 to 6 months for mild cases, and 6 to 12 months for severe cases. 1. Nerve root edema: if there is no limb swelling and numbness before surgery, but there is limb swelling and numbness after surgery, the nerve root edema is considered to have not subsided, and the symptom will disappear gradually in about 2 weeks. 2. Preoperative swelling and numbness of the limb is relatively light: if the limb itself has swelling and numbness of the patient before the operation, the specific recovery time needs to be based on the spinal cord injury, the injury is light, generally within 6 months can gradually return to normal. 3. Preoperative swelling and numbness of the limbs is relatively heavy: spinal cord cervical spondylosis is a common symptom of limb numbness or walking unsteadily, tread cotton feeling, chest and abdominal girdle feeling, these are the spinal cord damage, degeneration performance. Surgery can relieve the compression, but the spinal cord damage has to be repaired on its own. In some cases where the compression of the spinal cord is more severe, the recovery is slower and takes 6 to 12 months to recover.
