Having open heart surgery isn't that hard, as your asleep during the whole thing.
The hard part is recovering and being awake the first 4 days after the operation.
These few days will be the hardest days of your life, try to sleep them away.
But after you make it past these few days, nothing can be as hard or painful,
it's all down hill from there.
Removing the chest tubes, is sorta like ripping a straw out of a McDonalds cup.
The thought if it may be painful, be it really wasn't that painful, it was more of a very weird feeling.
Everyone is different, but I found talking about the operation during the first few weeks made me sweat, feel pain, weak, and sick. I know your friends and family will want to hear everything that happened to you, but you may want to wait awhile before going into such graffic details.
After my surgery I could feel my heart beat funny, like a hiccup of pain, this I was told was normal, and as time went on a few weeks later, I no longer felt it.
Getting in and out of bed was always the hardest. You don't want anyone to help you, as them touching you will hurt more. I know you must be using the hugging pillow method, but I did it by inching sideways till I got to the edge of the bed and somehow using my legs off the bed to lift my upper body in a weird maneuver. I might have looked like a weirdo, but it hurt less.
When you get home, you will be tired alot. Even tho you will be able to take care of yourself, it would be nice for someone there for the first couple of days to make some of your meals and deal with things you might not feel up to.
After a couple of days, you should be alright left at home alone. I don't know the age of your son, but if he takes a lot of work to take care and/or stresses you, you might need help taking care of him for a couple of weeks.
Remember you can't lift things for awhile (like kids), your weak, plus the chest bone they cut will need 6 to 12 months to completely heal. In the begining, lift nothing more then a gallon of milk, after 2 months you shouldn't lift more then 25 pounds.
After 2 or 3 months, most people can return to work, as long as it's not heavy physical labor.
