Bests & Worsts Reviews from Amazon

I’ve been dealing with neck pain for quite some time and I figured I was sleeping wrong or some thing else. I found this product And figured I would give it a try. When I first received it, I used the item as indicated with my knees up and gently put my head back over the product. I have to say in the beginning it did feel good with some pain, but the type of pain where you think it is working. After I was done I got up and my neck was a little sore but I figured maybe it will feel better in the next hour or two. I have to say it may have actually helped but I am not 100% sure. The problem occurred tonight: I did the same exact thing as I did the first time, but this time when laying my head back something felt different and I heard a slight crack. Laying there I was perfectly fine, but when I tried to get up I was physically unable to. I was in so much pain and literally felt paralyzed. I had to try for nearly 10 minutes by using my hands to pick up my head, having pulsing sensations of pain and falling back down. I eventually rolled over to my side and slow got on my knees with a downward dog like pose. My head would not move! My neck was completely locked and I was unable to stand up straight for another five minutes. I have no idea what happened but I am now sitting in a hot bath trying to relieve the pain and get some mobility back. My neck was 10 times better prior to using this this time. I caution anyone to really look into this product and try an alternative.
