Hello,
Your symptoms can be indicative of gastritis, 
acid reflux, 
indigestion or GERD. You can take PPIs, one stat when needed. If it is due to indigestion or acid reflux, you will get relief. However, such symptoms can also be caused due to MI or developing coronary artery disease, CAD. You are suggested to get clinically examined by a GP/Cardiologist, Get 
stress test, EKG, Echo, X-ray, blood sugar (F/PP), 
Urinalysis, lipid function tests, etc., done.
If any type of developing cardiac ailment is detected , it will be accordingly treated. You should stay away from addictions, drugs, alcohol or smoking. If obese maintain healthy weight. Do regular walking. Cut on sugar, stay away from 
trans fat, refined flour, full fat dairy products, red meat, etc. Take more of berries, fruits, veggies, nuts, etc.
Take care. Hope I have answered your question. Let me know if I can assist you further.
