I have had a triple bypass done on may 23rd this year. I have slowly been getting better with diet and exercise. the last couple of days, i feel tired, and today when i got out of my car at a local store, i had pain in my left arm, and across the middle of my back. after i sat back down in the car, the pain quickly faded. I have had no further pain. that was several hours ago, and i m still fine except my ears are ringing.
