I have had consistent sharp pain in my shoulder for about 30 years. When I went to reach for something, a jabbing pain would shoot in my shoulder. While I was in the EE system, I felt a nagging pain in that shoulder. I was only in the system for one, 2 hour session, and after I left, I noticed the pain had gone away. In fact, the pain has never returned and I now I have no problem using that shoulder! Astonishing!
