Hi Kathy, my husband had similar surgery February 2003 and 33 IMRT, finishing May 16, 2003. He went through physical therapy to regain better use of his shoulder and arm. I insisted that he go because he did not think it would make a difference. When he started he could not lift his right arm higher than his shoulder but after the therapy he lifted it all the way up. He is not as good as he was before surgery but there has been a big improvement. He is back playing golf very well,gardening and I am so glad he can go back to doing something he loves, I am proud of him. Don't give up, try some therapy, there are exercises you can do at home, but you have to be disciplined. Good luck.
