The root cause of sciatica is typically a result of a lumbar spine disorder that puts pressure on the sciatic nerve. This can include a herniated disk, degenerative disc disease, spinal stenosis, or a spondylolisthesis. These conditions can cause inflammation, pain, and sometimes numbness along the path of the sciatic nerve, which extends from the lower back down through the leg. Identifying the specific underlying issue is crucial for targeting treatment and finding relief.
