Aww interesting because my doctor gave me the option but said I wasn't a good candidate. He said that the block was risky where the shot would be given and that it would work for only eight hours and in that time slot I would have to exercise like crazy...only fo have the pain come back with a vengeance.
He did warn against astrophy and said for me not to try and give into non movements of arm and leg.
But the monster has spread and ldn helps minimum.
