JAMY, sorry you're in so much pain. A few things that help me sometimes:
-- avoiding aggravating positions and movements, obviously!
-- letting a warm shower run over tight muscles
-- sleeping in a recliner
-- keeping arms supported on pillows on lap
-- gentle stretches, as mentioned earlier...laying on my back for a few minutes with a small pillow between shoulder blades sometimes helps open up the area and reduces pain for me...but I can't stay in this position long, and sometimes it doesn't help.
-- keeping pressure off the shoulder blades, as mentioned (no hard-back chairs, or a pillow behind your back).
-- try to avoid long car rides, if possible
-- distraction, as mentioned, with a movie, music, reading or books on tape...my library has a program where you can check out e-books and listen to them on your computer. This way I don't even have to go to the library to get a book.

Hope things improve for you soon!
