Does Acidity Lead To Raised Heart Rate And Numbness In Arms?

mOSTLY AT NIGHT, i HAVE A FEELING THAT SEEMS TO START JUST BELOW MY BREASTBONE , CAUSES RACING HEART, AND A TINGLING/NUMB FEELING IN ARMS. HAVE RECENTLY HAD BLOOD TESTS, SCAN OF OSOEPHAGAL AREA, X-RAYS, VISIT TO GASTROENTEROLOGIST, WHO SAYS i PRODUCT TOO MUCH ACID AND HAS GIVEN ME MEDICATION FOR THIS. IT HELPED FOR A WHILE BUT NOT SO EFFECTIVE ANY LONGER. DOING EXERCISE, CUTTING LAWN, ETC DOES NOT PRODUCE ANY OUT OF THE ORDINARY SYMPTOMS. I AM A 75 YEAR OLD WOMAN.
