I have/had stenosis, bulging disks, osteoarthritis, just to name a few issues.
I had radio frequency ablation several times on various parts of my spine.
I NEVER found them to work.
They were uncomfortable and didn't work so that pissed me off.
Now, that was ME!
I have numerous issues and we are all different.
It is my opinion that when nothing works, like shots, it's time to move on to something that might.
Sadly, we have to be our own trial subjects since we all react differently.
