Our spine goes through a number of changes as we age. Some are inevitable, while others can be treated to ensure you stay active as you age. Spinal stenosis happens with the small space in your spinal canal begins to narrow or become compressed. This leads to pressure being placed on the joints and discs in the backbone as well as the nerves running from your spine to your arms and legs. It can occur in the upper, mid, or lower part of your back. It is most common in the lower back and neck in those over the age of 50. Spinal stenosis can be treated or halted easier the sooner it is diagnosed. If you have symptoms of spinal stenosis, it is important to seek treatment right away.
