in short term muscles will recover fully....nerve paths only regenerate at 1mm per year- if they do....test and GH are the only known drugs to regernerate nerve paths (test is only marginal, but does work to a point)...this is only needed in extreme cases such as mine was....my nerves were allowed to die and surgery was over 1 year later....bad deal..Killah has to stay on top of his treatment,until the disc repairs and does not interfere with the nerve pathways.... very important.
