question: I have been experiencing shortness of breath more frequently lately and excessive sweating even when Im just sitting around.  I am a 40 y/o/f, smoke approx 3/4 pack a day, and recently (since February) started working out and running.  For the last 2 weeks, on top of these symptoms, I have been extremely tired to the point that I dont feel like working out or doing anything.  This afternoon I took a nap.  I was woke up in the middle of my nap feeling like I was suffocating.  I just couldnt catch my breath.  I sat in front of a fan coughing and trying to breathe.  Since then I still continue to feel like I cant take a deep breath, Im having heart palpitations, and at times have what I think are chest pains.  Sometimes theyre sharp and sometimes it just feels like someone is squeezing my chest.  Also for the last few days when I breathe, it sounds like I have bubbles when breathing.  What could these symptoms mean and should I go to the ED tonight or wait to see my family doctor tomorrow?
