I spoke to my neurosurgeon today who ordered the BP block. Apparently the anesthesiologist just confused me since he was more focused on the more longer term relief over a few days rather than the immediate relief that would indicate the block was positive. Because I did not feel any pain while I was numb for several hours, it is supposed to mean that it worked for me. My neuro is sending me to another doctor to re-do the block specifically to the lower trunk since this other one let the medication go to all trunks.

It didn't last for me, I am in just as much pain as I was before the block by today, but for some, it can have a little longer relief. My neuro also said the scalene block is more general and wouldn't help specify how much a role the BP is playing, which is why he is not recommending that for now. Makes a lot more sense to me now
