No, I'm not really aware how 'long' a block is supposed to work. I was told, in my case, that it may last a week to a few months. It lasted a month or so for me. I know because the side I had the block done on tolerated the pec minor release (and scalenectomy) very well, until it wore off... then it was angry! The side done without the block didn't tolerate the release very nicely - bruised, burning and angry from surgery onward.

If you aren't ready to trade sets of symptoms, I'd suggest that you not do it. It shows you may have enough functionality to manage the symptoms "as-is".
