Thanks for writing your query.
In addition to cardiac pain, other common cause for chest pain
is due to acidity and gas or GERD (Gastro Esophageal Reflux Disease
). If your repeated ECGs and blood reports are normal, your pain indicates more towards acidity and GERD as a cause.
You can take antacid like Ranitidine
150 mg twice a day before meals along with Domperidone
Following some precautions will help like :-
1. Avoid spicy and oily foods.
2. Donot miss a meal.
3. Avoid emotional/mental stress.
4. Avoid cigarette/alcohol.
5. Donot self medicate, especially with pain killers and steroids
Also get yourself examined by a Physician.
I hope this is helpful to you.
