To OP[Original Poster]:Re-read (or read if you managed to miss them) the stickies on this the beginner's forum. Read the articles that are linked in the stickies. [In case you are totally oblivious the stickies are the first 4 posts on the Beginner's forum].
If you have a genuine shoulder injury I would get in touch with a physiotherapist and get that sorted out. Hopefully it is not serious and can be fixed.
To everyone else: Do you think the beginners read the stickies before they post? I'd say if they actually did read them carefully there probably would be no activity on this forum.
No they don't read them because 9/10 of the population would rather have the information spoon feed to them than take a hour or so to actually read a few articles and start experimenting... But, I still think this forum would be used because sometimes there are some decent questions asked.
