Spinal stenosis, especially lumbar spinal stenosis, is a very common disease. The disease can cause symptoms ranging from mild to severe such as: back pain and sciatica, which can spread down both legs causing paresthesia (numbness and trembling of the legs), sometimes muscle paralysis and sphincter disorders, urinary retention...

Spinal stenosis often progresses over a long period of time and leaves behind chronic pain. Surgery for spinal stenosis is only performed when other treatments do not work.
