I used it on my knees and lower thumbs a lot. Now I don't have to use it as often. If I am going on a hike or an extended physical activity, I pre-treat and voila, come back with no pain! I had one of my relatives, who participates in dancing competition, use it after having cripling knee problems and she was a convert, so much so 3 more relatives bought one each. THIS IS NOT FOR SEVERE PAIN.
