I feel out of a car when I was two. I was hit by another when I was seven. I was rear ended in 1971. My body was a wreck and I had been going to chiropractor every other week just to be able to keep moving. My neck would move about 15 % of what it should have. I had constant eye pains and headaches. I had a compressed disc in my back for over 30 years. Four years ago I found out how to release the muscles in my neck and back and legs, and arms to get rid of what pain I was having and after over 50 years I am first living without pain. It's what I found that did the releases that got rid of my pains that the physical therapy, dr.'s and chiropractors never addressed that I am passing along in my answers. After 30 plus years of having a compressed disc and seeing it gone after releasing my back muscles that has helped me understand the muscles. That and my courses of anatomy in vo-tech.
