I just had to let you know my experience with RTPR.. I hit my hand with a hammer right above the thumb joint. You know those stars and birdies that circle the heads of cartoon characters? Turns out they're based on real life! hehehe I put some RTPR on it and the pain subsided a great deal...Then about 2 minutes later, I put on a second layer and the remaining pain [was relieved]...I've used RTPR on my knees and back and neck and it was really great, but this was just a stunning result on the hammer hit. This product is AWESOME!
