hi there it,s so strange that you posted this yesterday..and i went to the doc just yeasterday to reconfirm thats its just indigestion and acidity and not a heart problem...the last week was hectic for me..travelling too much,irregular timings for food,i was living off tea and sandwhiches whereever i could grab one..the result..major attacks for 3 days..i finally had to go the doc..and as usual she,s given me a course of antaacid and i,m already better today..acidity has the capacity to make one feel nausea,give chest pains,block the ears..and hence frighten us and start the attacks all over again...and acidity only happens when we have indigestion due to bad lifestyles...hope this helped..love sanju
