Query: Gave me Pain in my neck and shoulders

This pillow was recommended by my Chiro so I trusted his judgment. It was terrible. I got neck, shoulder and upper back pain. If you sleep on your stomach, FORGET IT! I tried returning it after 3 weeks of trying it out (I was trying to give it the benefit of the doubt) and was turned down by the seller because of the nature of the product. I don't recommend if you have issues with your neck and shoulder and obviously if you sleep on your stomach.
