Thank you, dear Lj! I have been using coconut oil but I will switch to another oil as my feet are always icy cold (nerve endings problems).
Refined sesame oil is considered to be more warming, almond oil is also helpful, and you could add some warming essential oils (not too much). Spicy EOs like nutmeg, cardamom and ginger would be a nice blend. I used to get very horrid nerve pain in areas of skin, usually where the skin is thinner. It would last usually for a few days then go away. A friend made a salve with EOs of cinnamon, cardamom, clove, ginger and black pepper, in small amounts - it smelled great - and it took it away. I should make that up myself. That might help your feet.
