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.

@glokart1957, I use this for my piraformis syndrome. I have been using it for several years. I suppose it helps some, but I do not use it as much as I should. I usually put on in the morning after showering. It is a pain (no pun intended) to put on during the day after I am dressed. If my pain is bad at night, I will apply again. Gosh, having pain a year after your replacement seems odd. I don't think it can hurt you, but that is strictly my opinion. Best of luck to you! @joybringer1
