It is good to see you again. I am so glad you had a moment to stop by
Stenosis and the treatment depends entirely on the "cause" and the area of the spine effected. IE Herniation, fractures, deformities.. So, the treatment is based on the cause/area and usually the most non invasive measures are tried first, unless it is something that needs to be addressed surgically.
When you were diagnosed what did your Doctor say was the cause? What part of the spine was the narrowing located at? Does he/she know that your current medications aren't helping? You might need something a bit stronger to help with the pain.
