I am a patient who has had a long history of chronic neck pain. I never considered the idea that the pillow I was sleeping on contributed to my pain and tightness. I tried a variety of pillows that made no change in my neck pain until I came across Dr. Hall's PILLO1. I am not even slightly exaggerating that it has CHANGED MY LIFE. Though it felt unnatural at first and took a couple days to adjust, I began to feel relief after 2 nights of using the pillow. I now wake up without pain and stiffness! This is the pillow of all pillows that everyone should own to help with existing pain and also prevent neck and back problems. I am addicted to this pillow and confident that this pillow will help anyone.
