Unlike transplantmommy, I didnt have any incision pain. I did have chest pain though, sternal. When they started lowering my pain meds and changing them is when the pain started. It was like there was a boulder lying on top of your chest. That was my most painful part. It last about a day or two.
But like the last two responses mentioned. The chest tubes are ridiculously uncomfortable and it hurts alot when they pull them out. It starts to feel alot better as soon as they get them out though.
