Hi. I'm on a compounded topical lotion for my foot and hip pain due to SFN. It helps for my feet. It's a combination of amitriptyline, ketamine and lidocaine. It works great for me at night. I put it on my feet and then put on socks and my pain subsides so I can sleep better. Unfortunately it's expensive and my insurance does not cover it. I pay $108 for a small amount in a pump container. The container is probably 1/2 the size of a voltarin tube.
