I am 25 yrs old I have been dealing with back pain, since i was 16. I have had 9 injections, and 1 surgery, then 2 injections after that. After each injection the pain for me was unbearable, and it was that way every time. I agree with toolmaker though Try it, itmay help you. Good luck.
Give the injections a try they may help you.My only suggestion would be that you insist on being sedated during the procedure.
