Piroxicam gel helps with pain & inflammation?

Hi, does anyone know anything about piroxicam gel or has used it? I found some info online on how it can help with pain and inflammation. http://www.skintherapyletter.com/derm_news/2007.7/3.html Where can you buy it in the U.S.?

Looks promising, Is it FDA approved? Whats in it? How big of an area can you use it on? On second thought:

Maybe not such a good idea…

Wouldn’t icing the area for 20 mins have the same affect?

How is this different than using a numbing cream like EMLA which is popular?
