I have GBS/CIDP since 4-2011/ then CIDP 8-2011 and have tried lots for the pain of Peripheral Neuropathy: Cymbalta, lyrica, gabapentin, neurotin and all have little effect. I get IVIG @ 110mg every 6 wks, And am on cellcept @ 1000mg daily. My question is has anyone had any pain relief from METANX. Greg
