Lately, as in the past week or so, whenever I have a cigarette I feel as though I am exhaling too much, and can feel a cold dull feeling washing over the left side
of my chest
. Is this my lung
, my heart, perhaps just the muscle? I do not excersize too often, rarely in fact. My girlfriend was recently in the hospital for a heart issue, where they did an ablasion due to an extra pathway that was causing her heart to get up to 200 beats a minute.
