Why can't you have cold food or drinks when taking oxaliplatin?

Increased Neuropathy: Patients report severe weakness, numbness, and tingling/shocking sensations after minimal exposure to cold. In some cases, the effects are startling - they have been described as feeling like spasms in the throat. Some find that the side effects decrease after warming or massaging the area. However, cold exposure during treatments may having lasting nerve effects, up to 14 days after infusion.
