I was as skeptical as some of you as well. As a medical professional, I hadn't even heard of Real Time Pain Relief. I stubbed a toe quite severely and the swelling caused me to walk differently than normal, which in turn made my knee extremely painful while walking. An ICU nurse commented that he had a product that was good for aches and pains. He gave me some samples, and they worked great!! I ordered some RTPR and the foot cream from him and expected to see him within a few days. That was not the case as we were scheduled at different hospitals, the pain was quite bad for at least a week, before I got a hold of him and my order...I have since placed a large order and won't run out next time. I plan to share my samples with my elderly parents, one with back problems, the other with shoulder issues. Great product!!
