I am 47, female, non smoker, with mechanical aortic heart valve since 2010, about 40 lbs overweight and high BP. I m having chronic chest pains ( heartburn?) . Eating approx 20+ chewable antacids a day which only temporarily relieves chest discomfort for a few minutes at a time. When I bend over (to tie shoes, pick something up etc) the pain in my chest is almost unbearable until I straighten my upper body. Acidic foods, drinks, red sauces etc intensify symptoms. Also experiencing nausea and vomiting randomly.
