Diclofenac Sodium Topical Gel

[Starbrite]

My Podiatrist recently prescribed the subject medication for a foot problem and in research, I find that it "could" cause harm to the kidneys. Does anyone have any thoughts on this medication? It is supposed to mask the pain by shrinking the nerves. In elderly patients it has caused ESRD.

I'm curious to find info on that too, since I've been told to use it for arthritic pain. I think research is in order. Information that I have found on it warns of use in impaired kidney disease. But can enough get absorbed to advance kidney disease?
