Radiculopathy
When the nerve roots that travel between the vertebrae into various areas of the body become pinched or damaged, the resulting symptoms are called radiculopathy. A common cause of radiculopathy is narrowing of the space where nerve roots exit the spine, which can be a result of stenosis, bone spurs, disc herniation, or other conditions. The pinched nerve can occur at different areas along the spine: cervical (neck), thoracic (upper back) or lumbar (lower back). Common symptoms include muscle weakness, numbness, and pain.
