If foraminal stenosis creates pressure on the spinal cord or a spinal nerve root, a variety of symptoms can develop, including pain, numbness, tingling, muscle weakness and spasms. The nature and location of the symptoms vary based on the site of the affected foramen. More specifically, the symptoms can be localized or they may travel through the peripheral nervous system and radiate along the path of an affected nerve root. For instance, foraminal stenosis in the cervical spine can lead to symptoms in the neck, shoulders, arms and hands; nerve compression in the lumbar spine can cause symptoms in the lower back, hips, buttocks, legs and feet.
Cervical spinal stenosis can be far more dangerous by compressing the spinal cord. Cervical canal stenosis may lead to myelopathy , a serious conditions causing symptoms including major body weakness and paralysis.  Such severe spinal stenosis symptoms are virtually absent in lumbar stenosis , however, as the spinal cord terminates at the top end of the adult lumbar spine, with only nerve roots (cauda equina) continuing further down.  Cervical spinal stenosis is a condition involving narrowing of the spinal canal at the level of the neck . It is frequently due to chronic degeneration,  but may also be congenital or traumatic. Treatment frequently is surgical.
