Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. You are assuming that your chest pain / heaviness is due to acidic problems. You could be right. Acidity and gas inside stomach due to indigestion develops pressure against diaphragm. Due to this pressure, diaphragm is pressed upwards and the organs inside the chest walls / rib cage is pressurized. Chest tightness / pin could be due to this reason. Palpitation could be associated with anxiety arised out of the chest pain / heaviness. But it is always better to be in the safer side. Consult a doctor who shall determine what is wrong with you. There should be proper diagnosis for proper treatment. No self treatment, no self medication please. You can have garlic and ginger raw alongwith food to cure acidity and indigestion problems. Hope this answers your query. Available for further clarifications. Good luck.
