Sciatica - Diagnosis
Who gets it and why?Disc degeneration results from the natural aging of the discs between the bones in the spine.
In the vast majority of cases, sciatica is caused by a herniated or 'slipped' disc, which can put pressure on the sciatic nerve. Also, the disc material contains an acidic chemical irritant that can cause nerve inflammation.
Less common causes include spinal stenosis which is a narrowing of the nerve passages in the spine, a spinal injury or infection.
Your doctor will review your medical history, a physical and neurological examination, and if warranted, x-rays, CT scan and/or MRI studies. Sometimes you can be given a pain diagram to illustrate the pain distribution and sensation.
