Topical Magnesium Lotion for Feet

Yesterday I had an Integrative Medicine doctor encourage me to try rubbing a topical Magnesium ointment on feet, saying she’s heard it’s an anecdotal remedy for neuropathy feet, especially if they feel like you’re walking on gel pads or bubble wrap and may feel wobbly for balance (not pain). I’m never opposed to trying anything at reasonable costs if it seems to have merit, but while I’m googling where to find it, I thought I’d throw it out to this group and see if anyone has tried it and what results they think they got from it? Thank you 🙂
