Ask them to slow the oxali infusion. That might help. (They slowed mine to 6 hours.) There has also been lots of talk of a calcium/magnesium infusion during chemo to minimize the effects of the Oxaliplatin. The colorectal forum on the American Cancer Society Cancer Survivors network has lots of information.
I used plastic utensils - metal hurt, and kept gloves by the fridge. My husband warmed up the car for me so I wouldn't have to deal with the cold, and we kept the house warmer than usual. My fingers would shut down at 68'.
The effects are not permanent, but they are a nuisance.
