Spinal stenosis occurs in the back/neck (spine) when the space available for the spinal cord or nerves begins to narrow, leading to pressure being placed on various structures in the spine. A condition like spinal stenosis can occur in the upper (cervical), mid (thoracic), or lower (lumbar) spine. Onset of symptoms is generally insidious, and depending on the affected locale, symptoms can be bilateral or one sided. Walking is classically problematic with stenosis and flexion is typically a position of relative comfort. Symptoms may include numbness, weakness, pain or cramping and can be felt throughout the back (spine), down limbs, or in the neck. Spinal stenosis can be seen in conjunction with osteoarthritis, disc degeneration, and scoliosis. Symptoms can be vague and are often primarily sensory. In certain patients, epidural injection may be helpful as a temporary measure. Aquatic therapy may also be helpful.
