I broke my elbow a long time ago and I have no radial head and just recently I have been experiencing really bad pain and unable to move my wrist. I also broke my toes at the beginning of this year and the pain has been so painful but since wearing my Trion Z ultra bracelet I am so happy and pain free. I don't care if it is in my head but I do not believe it is as the pain has gone and my life is much more happy
