I am a 35 female. I have had these episodes, about 5-6 in the last 3 years. The pain is a tightening pain that starts in my left side of my jaw a goes down to my chest just under my breast. The pain/tightness lasts about 5-10 min. After the pain fades I become completely exhausted and sleep for a few hours. I just had an episode on Friday and It was different because my left side of my lips were numb and I have had a headache since after it happened on Friday so 3 days so far and I can't seem to get energy to do anything.
