Nerves Problems in Hands and Feet

Hi - my husband has peripheral neuropathy - his feet and legs feel as if he has an uncomfortable sock on them and he has loss of/different sensation in his fingers.  Apparently this is a side effect of oxaliplatin which was used on his previous course of chemotherapy.  He has gabapentin pills but they don't seem to make much difference.  Does anyone have any ways of dealing with this? does it ever go away?
