Pain
"I am highly alllergic to internal intake of NSAIDS.  The gel has been tried as an alternative.  I have had bilateral knee replacements and suffer from RSD.  I thought the gel was helping the knees.  However, when I was off of my narcotic protocol for
a period of two weeks, I discovered that Voltaren did not work.  I was sad that it did not work because I am seeking a good alternative to narcotics."
