The first line of treatment for lumbar spinal canal stenosis is treatment using drugs that reduce pain, improve circulation, or relax the muscles.
Depending on the symptoms, a corset may be used to ease the burden on the lower back. Heat therapy, in which heating the affected area to improve blood circulation and relax the muscles alleviates the pain, and exercise therapy consisting of stretching and muscle-building exercises may also be used.
An injection therapy called nerve block is also effective. If these treatments do not produce an improvement and if the condition is interfering with everyday life, surgery may be performed to cut out the bone deformity that is the cause of the stenosis.
