Yea! My twin! It worked again! This is simply the best news you could hope for!
keep moving that arm when you can, and start some stretching exercises when the doc lets you. I was told not to worry about
it and still have some tightness when I stretch that arm. I have found that even years later, the stretching helps, and I have less tightness now than even 2 or 3 years ago.
Rest up and savor the good news!
