Hello dear
I understand your concern
Your symptoms could be due to muscle 
twitch, aortic pulsation, acid reflux/
indigestion, 
anxiety.
Just wait and watch, it will disappear it own.
Meanwhile avoid 
stress, take healthy diet, drink plenty of water, do regular exercise like  walking and yoga, 
Take small frequent meal rather than large meal
Avoid spicy/oily/fatty food
If problem continues after week then consult the general physician and undergo detailed examination, chest Xray, ECG and USG abdomen to rule out other cause.
Hope this may help you
Contact HCM for further health query
Best regards
Dr. Sagar
