Discogenic injuries occur in the lower lumbar and lower cervical joints, the lumbar (lower back) being more commonly affected that the cervical (neck) joints.
The injury usually occurs with a lifting movement where the back is flexed and rotated. Usually something is felt at the time, but the pain may not be too severe. It is usually worse getting out of bed the next morning. The severity and extent of the symptoms indicated the severity of the injury. It can vary from pain felt across the lower back to pain radiating down the leg along a neural line.
It is important to get to your physiotherapist as soon as possible to help with the pain. You will also need to start an extensive core strengthening programme to strengthen your back around the area of weakness
