My thoughts are with you
(see my post in the Self Esteem thread)

The main things are:
1. Keep your mind and spirit positive and remember that the human body is at all times making its own physiological effort to return to optimal functioning and all systems go. I made a point of watching cycling on tv (esp the Tours) after both my mastectomy/chemo and in recovery from a tractor accident involving near-death-by-squashing
2.Do the physical therapy excercises with Great Intention. Shut your eyes if you think you are not progressing. (You don't feel so pathetic if you can't see)
3. Don't forget about the rest of your body. I had a massage every 2 weeks and went for long walks.
4. Take pain meds. Otherwise you really get demoralised

Go, Lady, go!
