I just had 2 about 2 months ago. The second one was about 10 days after the first. It has help my stenosis pain and back related issues.
I would also recommend under fluroscope. (sp?). I have had them both ways but would only do it with fluro.
I had several a few years ago. One or 2 helped then. They are said to last around 3 months.
I also think in depends if they put the shot in the place where you are having the most trouble.
This one has helped me and enabled me to walk longer and more often without griping pain.
I undersatand one should only have them pnly 3 times a year.
Hope this helps.
Let us now how you do.
