My pain doctor prescribed Diclofenac sodium for my PN over a year ago. I use it on my feet whenever I need to wear shoes and on my hands when they are painful. It does a pretty good job of relieving my pain in those areas. It is now available full strength under the brand name Voltaren and I have just tried it and it works just as well. I would use it on my feet at bedtime when I frequently have pain but I find ice packs work for me and I only need them for about 15 minutes and then my pain goes away for the rest of the night. BTW, I take gabapentin 3x a day and tramadol as needed for break through pain. It's not perfect but makes my life somewhat manageable. I could not do with any one of these.
