Yesterday morning, I was sitting in bed with my husband watching the news, and enjoying a cup of coffee and a cigarette. I started getting a heavy feeling in the middle of my chest, this progressed to a painful squeezing sensation on the left side around my heart. I felt as if I was about to loose all my bodilt functions. I felt as if I was going to pass out, very dizzy, and drenched in a cold sweat.Very short of breath , much difficulty breathing. My hus band put one of his nitro pills under my tongue, and after about 5 minutes,I stated throwing up.But the pain went away.It left me totlly exhausted, and barely able to move, my left arm was very weak. I remained very tired all day, but today,I feel fine as if nothing happened. I am female, 51 years old,average weight,I do smoke.I do not drink . I get plenty of exercise. Did I have a heart attack???
