Hi Wayne... (Hi Ray! :)  ) you may also wanna take a serious look at your 
posture and neck health. I have found that these types of nagging shoulder 
problems can frequently be traced to poor posture and body mechanics (like on 
your computer) that can refer to the shoulder via the neck and upper back....
Sound familiar?
A very large component of back and neck problems is POOR POSTURE!!!
Just a suggestion.....
