"i love this gel. just 10 seconds after i put it on an area with severe pain, the pain is gone completely for 2 hours. i couldn&#039;t believe it the first time i used it. i take some other strong prescription medication for knee and back pain and the medications don&#039;t do as good a job on the pain as this gel. i wish i could use it more than 4 times a day, but during my waking hours, it is a god send. thank you, thank you, thank you! i would do a commercial for voltaren gel anytime, for free!"
