Back in May 2012 I had an odd bout of pain, it was as if someone had beaten my upper back, I had pain that seemed to wrap around to the front causing what I would consider tightening in chest or sternum area, it lasted for 3 days,I did not go to Doctor or hospital, its a long story of husband out of town and daughter busy with two babies at home. Did not want to bother anyone. I did think I was having a heart attack, as I do have high cholesterol.
