I injured my back overdoing it at a farm three years ago. Gentle Chiropractic and Applied Kineisiology has helped but the effects don't last for very long. For the past year, I wake during the night and in the morning with severe stiffness, weakness and pain in my lower back. I cannot bend over first thing in the morning. I tried this product on a whim because someone gave it to me and I was curious. I've never really had much "faith" in homeopathy. Well, let me tell you, I am a believer in this product!!!! Last night, I took it as directed every few hours and my nightly and morning pain had all but gone. No one is more surprised than me. I will never be without this product.
