Has anyone had experience with Voltaren Arthritis Pain Gel ?

Almost every arthritis cream, gel or liquid is a product that just distracts from the pain by causing either an alternative pain or cooling sensation. 

Menthol and others are counterirritants that work on   pain receptors by creating a cooling/warming sensation, and are intended to help dull the feeling of pain by redirecting.  None of these others actually reduce the basic pain.

Voltaren seems to actually work on the root of the pain.
