I had chronic back pain for years, after getting hit by a dump truck when I was younger. My back was so bad the other day, I’m talking on a scale of 1 to 10, I was more like a 20. I could hardly walk, I couldn’t bend, and every step I took my legs were giving out. A friend of mine told me about this patch after wearing it for two minutes my pain literally went from a 20 to a 1. I was amazed and two weeks later I still have NO pain. I am so grateful my friend told me about this patch.
