Welcome to Neuro Talk. I do use a lotion, that works great. It is a compound recommended by my orthopedic doctor and a physiatrist. I have PN or RSD.
Here are the Ingrediants, it would be worth asking your doctor about. Takes away burning and pins and needle like sensations.

KETAMINE/CLONID./GABAP./IMIPR./MEFEN ACID/ TETRACAINE (5) 10/0.2/6/3/3/2%CREAM..
This is not 100% effective but it does help. ginnie
