Welcome to Health Care Magic..
The symptom of feeling tightness in chest and constant burping indicates indigestion
of foos substances ..
I would recomend Mucaine
gel 10ml after food thrice daily will help you along with pantoprzole 40mg to reduce symptoms.
Avoid caffine related products and have a balanced diet to recover faster to normal life.
Hope this information helps you to have healthy life.
Thanks and Take Care.
