Does this actually make things worse?
I love the feel of digging in to those sensitive areas on my back.  This hook is as good as any you'll come across.  It is sturdy, versatile, and easy to use.  The only problem I had was that I eventually noticed a pattern.  Whenever I would use it, I would wake up more sore the next day.  Whatever muscles I dug into would be so tight the next few days.....it was painful.  I've basically stopped using this hook for that reason.
