I have had ch for years now, on and off, and for the past 9 months it's been agony in my neck muscles/bones. I have just found something that works for me and, believe it or not, it's a Hitachi Wand! It's intense and I've only used the lower setting, but massaging it all around brings me wonderful relief. Sideways makes the teeth rattle lol, but head on is great. Hope this helps for anyone.
