62 Female (smoker) - been experiencing chest pain directly in center of chest for about a week and a half - not consistent and doesn't last long (maybe a minute) - seems to come on more when I'm lying down. Experiencing on and off nausia . Also been experiencing sudden bouts of exhaustion, sleeping half the day away. Chest pain is not intense, no sweating, or shortness of breath.. so what could it be? thanks for any info....Michelle
