I read your article. The following are incorrect in my opinion.
Women use it more..(back injections)....I use it, am female and it works. I am staving off back surgery #3 and it makes me able to function and walk!
Crunching numbers and making statements about whether it is effective and that it is being done for $$ offends me.
You did not contact all of us who have been treated....instead you, again in my opinion, made a statement that may influence people in need of alternative treatments not to seek it.
If you have ever had serious back problems you would be able to speak from actual experience not the fact crunching you did in this article.
I have lost confidence in the information and opinions from this site and that is a shame as I originally felt JOHN HOPKINS knew what it was talking about. No I do not have the same opinion.
