The neural foramen is the opening between every two vertebrae where the nerve roots exit the spine. The nerve roots travel through the foramen to reach the rest of your body. There are two neural foramina between each pair of vertebrae - one on each side. Spinal Stenosis is a process of degenerative change to the bony structures within the neural foramen and may result in vascular and/or neural compromise. Symptoms may include loss of mobility, pain, decreased function, and referred symptoms to the lower or upper extremities.
