I love this stuff! I deal with aches and pains from run/walking road and trail races. Also, my age is a factor in what ails me. I apply the Real Time Pain Relief to my knee or foot or elbow (my three affected areas) and...I'm moving around with little or no pain and more range of motion in the affected area. Recently, my runner's knee popped back on the scene with a vengeance. I started applying the RTPR...I am SOLD on RTPR.
