There are sequelae of lumbar disc herniation surgery, but not all surgeries have sequelae. The sequelae of doing surgery mainly include the following: 1. chronic lumbar pain due to herniated disc, as well as the stimulation of surgery, local scar healing, scab formation, resulting in adhesions of surrounding tissues, chronic pain and limited activities. 2. the range of lumbar activities becomes significantly smaller, especially in patients with internal fixation surgery, because there is mobility between lumbar vertebrae, but after internal fixation restricts the activities between vertebrae, thus 3. numbness and weakness of the lower limbs cannot be effectively improved. surgery only relieves the nerve compression, but the recovery of nerve function needs itself, the earlier the surgery the less nerve function is damaged and the faster the recovery. The later the surgery, the more obvious the nerve damage, the worse the recovery, and there is even the possibility of not recovering.
