I HAVE A SEVERE PINCHING SHARP HEARTACHE WHERE IN I CANNOT EVEN TAKE BREATH FOR THAT MOMENT..IT IS LOCALIZED IN THE UPPER PART OF MY LEFT SIDE OF MY CHEST , IT LASTS FOR ABOUT 2 MINS. IT HAS HAPPENED EVEN WHEN I WAS EMPTY STOMACH AND HAD WARM LEMON WATER. IT HAS HAPPENED IN THE NIGHT ALSO BEFORE THE DINNER. I HAVE GOT BLOOD TESTS AND REPORTS WERE NORMAL,LYMPHOCYTES WERE HIGH ONLY I GUESS. SUGAR WAS NORMAL. I EVEN FEEL SHORTNESS OF BREATH WHILE SITTING TOO, WHILE CLIMBING UP STAIRS I ALWAYS FEEL. I GUESS IN THIS MONTH IT HAS HAPPENNED TILL NOW THRICE.
