I had open surgery Dec.18 2018 to repair a 5.7 cm tear in the root of the aorta. I am now worried about not having been in any type of rehab/exercise program following the surgery. I do get "winded" after going up and down stairs and need to sit down to catch my breath. I am still taking pain medication — only 1 every 12 hours now– but am tired most of the time. Is there a regime of exercises I can do to get back to feeling myself again? I would appreciate any feedback about recovery time and protocols following surgery.
