question: Hi I'm not having chest pain or shortness of breath at all.  But I've become paranoid about heart disease as it runs in our family history.  I have muscle fatigue especially around the shoulders and have not been sleeping well.  I see a massage therapist at least 1 -2 times a month.  I weight 260 lbs and am 38 yrs old.  I alos have IBS.  Since yesterday I have been having bouts of diarherra an am concerned its heart related.  Please tell me its not my heart.  I took my blood pres and it is 120/81 pulse is 85.
