Yes surely you can use these medications for above said problems but my advice is that if you are having the same problem since long you should consult doctor because the cause behind these symptoms must be ruled out. Else change of lifestyle & food habits may also resolve the problems. Being away from family may lead to continues ingestion of outside spicy & junk food, irregular timings of food, non intake of foods such as curd, buttermilk, which cause the acidity & above said symptoms. Try to regularize food timings, and inclusion of curd & buttermilk in food. Avoid alcohol & smoking if any . & Must have at least one medical consultation.
