It has been weeks, and you appear not to be having complications. If you were in America, your insurance would have already cut you off.
I only had lung cancer, and it was a quick operation to remove the tumor. My recuperation entailed just staying alive long enough to rebuild my strength and weight, along with being able to pay my bills.
I went back to work in a limited capacity six months after the operation, I had to, I needed the money to keep paying for my insurance and my bills. I only lasted nine months before I knew I had to leave, and my company was quite happy when after I used a personal leave to find a way to let me go.
As for my heart and circulation issues, stent operations are quite quick once you get scheduled for the operation. Five days afterwards you can resume your daily routine, as long as you still take it slow.
Cancer taught me that the health game is a "long," game, slow and steady progress, and don't be foolish. Stay away from smoke, bad foods, and get plenty of rest.
You appear to have snapped back quickly. But please remember that you body has been operated upon, even with modern medicine, your surgeon either had a good day, or you might have to go back.
Lastly, it always pays to treat every day with an extra enjoyment. You have been given a gift to keep on going. Some people do not take operations well, and new complications arise. So be happy with yourself, and smile each day. Life is really precious.
