I have idiopathic neuropathy in both my feet, no diabetes. I've had this for about 7 years & it's gotten progressively worse. I also don't take any meds for it. I found this Mayo Clinic post for the first time last week searching for some relief for nights - the burning & tingling keeps me up. It's exhausting. Someone here suggested lidocaine. I have been putting lidocaine pads (Salon Pas) on the bottom my feet (I 've tried everything & figured I had nothing to lose). It may be unique to me but I can't believe the relief I'm getting! These pads quell my pain and I can finally sleep through the night. Sharing this info as it may be helpful to someone else.
