Is Biofreeze Cream okay to use for neuropathy? Where am I not supposed to use it? Does it help with?

Absolutely use it. It also comes in a gel.
Just keep it away from your eyes and private parts of course. And wash your hands well after applying.
I was given a tube of this years ago by my sister in law, an occupational therapist. It used to be by prescription only. It's the best stuff I've found for neuropathy and swollen joints.
