Lee- I, too, had plenty of chest presure and some shortness of breath for the first couple of weeks post surgery. Everyone, including the docs told me it was completely normal, after all I had just been split open! ( 3 times in 12 hours for me, I had complications!) But it abslutely eases up. I am at 5 1/2 weeks post surgery. I am comfortably taking 2 30 minute walks a day for a totla of over 3 miles. My sternum aches still, and I have found that the more mobile I am while sleeping, the sorer I have become. But it is all part of the healing from being able to move more! I actually woke up sleeping on my stomach. I ached after that one! Keep at it. Some days are better than others, but each one, is one more of recovery. Take care- Candy
