I also had a triple bypass surgery in1991 and it got infected within a week. Back to the hospital for IV antibiotics and debreeding. I was in the hospital for 4 months. They took out my sternum, did the muscle flap and a skin graft as they had debreeded so much it couldn't be closed. I still have constant pain in my chest and back. I can not lift more than 5 pounds and I am very caeful about being in crowds. I can't stand anyone to touch my chest or back. I carry a pillow in the car to put under the seat belt in front of my chest. My doctor suggested that. Hope your father does well, Karen in Delaware
