I could turn my head right to left and was able to fully dip my head back - something I hadn't been able to do in 3 years. My lower back pain had become so intense that it kept me from doing the simplest of tasks like putting on shoes & bending to get the milk from the fridge. Now I can finally tie my own shoes and bend in a way I haven't been able to for years. These were huge changes for me. I'd even call them miracles.
