really does seem to work for pain relief.I have a neck injury and consistant neck pain. I wore a version of this necklace almost constantly for over a year and I felt that my neck was improving. Then that necklace broke and I threw it out thinking it wasn't really the necklace that helped my neck anyway but that it was just time that healed it. I'm quite a skeptic of such things. A couple of months went by and my neck began to worsen again, a lot worse. I bought another necklace thinking what the heck, still thinking the necklace really couldn't be part of the solution but I was desperate. So now after wearing this new one for a couple of weeks, day and night my neck is improving again. It's improving by a lot. I don't understand how this works, but for me it really does seem to work.
