Sciatica is difficult to cure completely. If it is primary sciatica, which is caused by inflammation of the sciatic nerve, there is a possibility of complete cure after medical treatment. However, secondary sciatica is generally difficult to completely cure because it is usually caused by spinal diseases, such as herniated discs, spinal stenosis, or even spondylolisthesis. In such cases, even after solving the primary disease, some problems may persist, continuing to stimulate the sciatic nerve, making it difficult to cure completely. If the sciatica is caused by spinal tuberculosis or a spinal tumor, the situation is even more complicated. Even if the primary lesion is resolved, it cannot guarantee that it will not recur. Therefore, sciatica is difficult to cure completely.
