Because these nerves travel to the hips, buttocks, legs and feet, an injury in the lumbar spine can cause symptoms in these areas such as pain, weakness, numbness, and tingling..

Because of how common this pathology is, it is important to understand the usual natural history of radiculopathy due to disc herniation. Acute disc herniations typically improves significantly by 6-12 we...
