title: By the way, doctor. I am a 73-year-old male. I've been diabetic for 50 years, and had a quintuple bypass eight years ago. I try to get an hour of exercise on a treadmill each day. While working out a couple of days ago, I developed a sudden sharp pain on my left side at about chest level, toward my back. Naturally I stopped, but I wondered when a person like me should call 911.
