Since 15 days I am going through gastric problem. I get burping, it starts with morning even on empty stomach and and even after taking meal. I am not having constipation but this burping creates uneasiness feeling, my chests sometimes pain and also sometime in throat also feels like acid reflux. I am not having heart burning, but burping is there. Earlier I had the problem in 2016, now also having the same. Can I take medicine named "happi 20mg" and "gutrex d".. Will it be okay for this. Last year doctor prescribed it. For this. If no please suggest medicine.
