Did he do it while you were awake using the fluoroscopy to pinpoint the area that gave you the best relief? It takes longer during the procedure, isn't fun, but in my experience gives much longer lasting results.

The meds also make a big difference--I don't remember what the options were when I last had one, but there are probably new options anyway, so you might want to research this. Some docs really only do these for diagnostic purposes--and yes, you just had further confirmation it is RSD/CRPS. Did he give you an idea of best case scenario, how long you'd get relief? If he wants to do more?

Is he willing to give you a Ketamine infusion? It's a simple procedure.
