Were you awake for the procedure? Did the doc use your feedback to pinpoint the location for the block?

I had stellate ganglion blocks done both ways. 1) Pain doc who performed them routinely. I'm fairly sure it was not a guided procedure. These were very hit or miss--some I got a few weeks relief from, some no more than a day. 2) Ex spine surgeon who treated it more like a surgical procedure than a "shot" and I usually received 2-3 weeks relief. Some people keep having them for years...

All blocks are not created equal.

Different meds can be tried as well.

Many docs use them as a diagnostic tool--they'll be happy with a day's relief...
