Don't be scared. I've had a pulsed radio frequency ablation in my lumbar area, not in the stellate ganglion area. It helped for awhile but I need it again. It stuns the nerve in order to interrupt the pain signals. You definitely want sedation for it.

Here's more info on RFA's:

If you have more questions, let me know.
