question: I am experiencing sharp pin prick type of pain in my chest, been suffering with extreme heat all day, no one else feels the heat this way today.  Feeling extremely tight and pressure in my chest.  No pain in my jaw or left arm.  Feeling like I want to vomit.  These hasn't gotten worse, but it was gradual to this point.  I am 52 year old female, obese and not on any prescriptions.  Had a cholecystectomy 09/2013. No complications since.
