I use Super Blue Stuff Roll On Cream for pain I occasionally have with my knees. Its very effective at getting rid of the pain and the cream has a very pleasent smell to it as well. Another plus with this cream is its a roll on bottle so I don't have to get the cream on my hands. Its not too strong like the other creams I have used that have a high percentage of menthol that feels like a burning sensation rather than a cooling relief of the pain.
I usually put it on first thing after I wake up to prevent any knee pain. The knee pain relief usually lasts all day but sometimes I may need to use it twice a day but it beats taking pain relievers in pill form when I only need relief in a specific area. Other ingredients in it are Emu Oil, MSM, and Glucosamine. Some people may take Glucosamine pills for joint pain relief but if you have only a few areas needed for Glucosamine this would of better relief because you get more Glucosamine absorbed in that one area.
If your interested in trying just be sure to start off being somewhat cautious with it as if you apply it too fast it can feel more like a burning sensation but this can be avoided.
