Your symptoms of stomach pain, tightness, bloating, tingling
and burning down the arms to hands are indicative of heart associated pain called angina.
Often the people make mistake of calling anginal pain as acidity.
Look for history of pain/tightness after exertion, palpitation
I would suggest you to go to physician as early as possible and rule out the heart disease
Doctor will take thorough history and take ECG.
Sometimes ECG might be normal in case of condition called 'Non ST elevation angina'
In that case, exercise stress test
will be recommended.
