What are radiculopathy and sciatica? What are the symptoms?
Radiculopathy refers to nerve irritation caused by damage to the disc between the vertebrae. This occurs because of degeneration ("wear and tear") of the outer ring of the disc or because of traumatic injury, or both. Weakness of the outer ring leads to disc bulging and disc herniation. As a result, the central softer portion of the disc can rupture through the outer ring of the disc and abut the spinal cord or its nerves as they exit the bony spinal column.
When nerves are irritated in the neck from degenerative disc disease, the condition is referred to as cervical radiculopathy. This can lead to painful burning or tingling sensations in the arms. When nerves are irritated in the low back from degenerative disc disease, the condition is called lumbar radiculopathy, and it often causes the commonly recognized "sciatica" pain that shoots down a lower extremity. This condition can be preceded by a localized low-back aching. Sciatica pain can follow a "popping" sensation at onset and be accompanied by numbness and tingling. The pain commonly increases with movements at the waist and can increase with coughing or sneezing. In more severe instances, lumbar radiculopathy can be accompanied by incontinence of the bladder and/or bowels.
