What Does A Constant Pain Between The Breast Plates?

A CONSTANT PAIN BETWEEN BREAST PLATE, ASSOCIATED W/ PRESSURE IN THAT AREA AND A RANDOM RAPID HEART BEATS FOR LONG PERIODS AT A TIME. PRESSURE NORMAL AND PULSE NORMAL; IRONIC, SINCE MY PRESSURE HAS ALWAYS BEEN A LITTLE HIGH AND MY PULSE HAS ALWAYS BEEN IN THE 60 S RANGE FOR THE LAST 3-4 YEARS; AS A 25 1/2 YEAR OLD. ALSO AN ACUTE CLUTCHING-SQUEEZING FEELING ON THE LEFT SIDE AND UNDER THE LEFT BREAST ATTACKING THE HEART. GROWING TIRED W/ LOW LEVEL ENERGY. ONE LAST THING- IT IS STRAIN TO EAT/ SOMETIMES MY SWALLOWING FUNCTION STOPS WHILE EATING-DOWN TO SMOOTHIES, BABY FOOD,SMALL HANDFULS OF FOOD WHEN POSSIBLE. I VE BEEN TO THE E.R. 8-10 TIMES IN THE LAST FEW MONTHS/ JUST SENT HOME; SEVERAL SPECIALIST ONLY - ONLY FINDS AN OVER-SIZE HEART, GALLBLADDER STONES/ HAVE TO HAVE HIDA TEST TO SEE IF THERE IS AN ISSUE; AN LARGE FYBROID. ALWAYS BEEN OVERWEIGHT ALL MY LIFE ALWAYS TRYING TO LOSE WEIGHT/ BUT SINCE THE ISSUE OF EATING - I VE LOSE 20 -25 LBS. IN 2 MONTHS. ALSO AS A BABY MY MOM SAYS I HAD A REFLUX PROBLEM/ PROJECTILE VOMITING- AS OF LATE HAS BEEN HAPPENING. PIECES OF FOOD WILL JUST FLY OUT OF ME A LITTLE BIT AFTER I EAT; OR SOMETIMES UP 8-12 HOURS SOMETHING FROM MY LAST MEAL FLIES OUT OR A LITTLE VOMIT. BUT MY OSCOPY SHOWED FINE AND STOMACH BIOPSY/ GOOD. SORRY SO LONG. THANK YOU FOR YOUR TIME. GOD BLESS.
