hello and pleased to answer you
first, the problem is that you are suffering from symptoms that mimicked heart problems.
second, your cardiologic check up is normal.
tertio, you are suffering from some digestives complaints (
acid reflux, nausea).
in another hand, The gastritis corresponds to an inflammatory alteration of the
gastric mucosa. There is no particular clinical picture of
chronic gastritis, and sometimes it gives the same symptoms as cardiac diseases.
for that, I m thinking that you are suffering from gastric diseases and perhaps with
helicobacter pylori infection, and I would be pleased if you check you digestive system at a gastroentrologist with an objective to do a Fibroscopic checkup. time to consult the gastoenterologist, please take Pantoprazol 40 once daily, and all your complaints will disapear in 3 or 4 days.
Polycystic ovary syndrome (PCOS) is not associated generally with digestive complaints, as GERD(gastroentero reflux diseases).
finally, are you using Metformin for PCOS, if yes , it can be responsible of gastric problem, and you must stop it, time to treat your digestives complaints.
May my opinion help you.
best wishes.
