I have had problems with my shoulder on and off for a few years, tried a few different treatments I found that the massage that helped but what really did it was the shoulder roll CD. A collection of very small movements that you wouldn't think would do anything! But I haven't had a problem for months. It started to twinge after I had flu, so I did the CD again and all loose again, so I will keep using it and recommend to others. Thank you Adam.
