Hi "tired of pain" I know exactly what your going thru. Its called the chronic pain merry go round. I've been going thru this for 15 yrs. Meds , shots , c-scans , mri's , and so much more I can't even remember. The one thing I do know is that I've had MANY injections. Now they will say they are really diagnostic but they are just groping in the dark. Especially nowadays since narcotic meds are frowned upon , hey it's injection time ! ( $ )

They are doing the same thing to me now , going to burn the nerves that they THINK may help your brain not feel the pain.

In short your lucky to get any kind of treatment nowadays with all the fuss about meds and insurance companies etc...

Back pain is one of the most difficult things to diagnose and treat.

Best of luck to you
