So I was using my massage chair the other day and my neck was feeling a little sore. I put the massage chair piece against my wall and pushed it up so it would reach my neck. It didn't hurt when I did it, it actually felt pretty good. It was kind of a weird sensation though, it shoot all the way from neck to my feet/legs. I just want to make sure I am not injuring my body when I am doing this. Also it is one of those massage chairs that has those 2 balls(I didn't know what else to call them) and spin in a circular motion going from top to bottom and the pressure isn't extremely hard, I would say it is about normal. Do not know if you needed to know that last part but whatever couldn't hurt, THANK YOU EVERYONE IN ADVANCE
