I sure don't envy you this surgery but you will feel so much better after the repair. Skip has had both shoulders done (I told him to be glad he wasn't an octopus!) and emphasizes how important the physical therapy is to full recovery. He did have rather explicit names for his therapists but gives them full credit for his mobility now! So hang in there and do your exercises.
OK--books suggested: Water for Elephants (Sara Gruen), Year of Wonders (Geraldine Brooks), anything by Jodi Picoult, if you are a dog lover--The Art of Racing in the Rain (Garth Stein) and The Story of Edgar Sawtelle (David Wroblewski)Kathy White
