I felt pretty heroic after having my 6-7 chest tubes pulled, it was not so much painful as just weird feeling. Kind of like getting a really big splinter in your hand, ok, not really. But having them removed was such a happy experience for me since I was more mobile and sleeping was so much more comfortable.
I remember my back was really sore and since I had so many chest tubes, sleeping was very uncomfortable. I asked for lots of back rubs and had some lidocane patches I wore daily.
Walking was the hardest for me... mainly because I wasn't walking much at all pre-transplant since I was on a vent for 3 months. My legs were atrophied, so walking and breathing with my new set of lungs was my most uncomfortable task, after 2-3 weeks I felt like a new person. But for most post trasplanters, I am guessing walking isn't so difficult.
