question: I've had a tightness and pain in the center of my chest that comes and goes for the last 2 days.  Tums don't help.  Sometimes it feels like someone is sitting on my chest or my bra is too tight.  I also have had severe gas in my stomach.  My mother died of a massive heart attach at age 65. She had complained of indigestion for a couple days prior to her massive heart attach.  I'm only 51, but I'm over weight... 5'8'' 240 lbs.   I hate to go see a doctor for just gas.
