For a couple of years I had severe aches and screaming shoulder pain that would wake me up at 3 or 3:30AM. Nothing worked, pills, pt,chiropractor, etc. Finally solved the problem with deep tissue muscle massage. It turned out that my muscles couldn't remember how to relax so when they got tight they stayed that way. I still have aches and the occasional pain, but at least the current ones are from identifiable sources or hard labor.
