I have a vibrating beat under left breast, from sternum down following left ribcage. Also a dull ache in the same area. I have been to ER twice and admitted once. Admitting physician thought Afib or blockage each time cardiac workup was negative. The first ER visit was Dec 2014, last was July 2015. Still have no answers. Antacids helps, Bentyl also seems to help. Gastro did EGD and ordered Barium swallow. Small Hiatal Hernia and little irritation at duodenum. This is very disturbing. I feel like my herat is going to stop. I feel like I'm having a hot flash that starts at my feet and proceeds to the top of my head, I perspire, feel nauseated and weak. Any suggestions?
