I had a thoracotomy 3 weeks ago and my surgeon stressed how important it was for me to walk as much as I could right away. Starting last week, I can walk a mile a day. I am doing it pretty slow...takes about 30 mins. Am I on track? Should I be walking more at this point? Do you know if it's better to increase my time or increase my speed? I still feel stiffness...but I think it's because of my incisions healing. Anyone have experience with this?? Please help!!
