Not so bad, so far.
I started 2009 with bursitis and “frozen shoulder,” which made it painful to use my right arm. And I am very right handed. I had surgery to fix it in late January and went through months of physical therapy to regain my strength and flexibility. It worked! I’m starting 2010 with full use of both arms. This is good. At my age, I’m grateful for a physical problem that can be fixed.
Of course, we’re planning to go skiing this month, after a 15-year hiatus.
