Thanks for writing your query.
After reading your post, it seems that the symptoms you are experiencing are medicine induced.
3 is a pain killer and can cause iincrease in acidity and gas production, if not taken along with antacid.
Antibiotics should be taken along with a probiotic
preparation because antibiotics tend to disturb the normal flora of useful bacteria present in intestine. These bacteria help in the process of digestiion and absorption. Loss of these bacteria can result in excessive gas formation and antibiotic indued diarrhoea
I would suggest that you should add antacid like Omeprazole
20 mg once a day before breakfast along with Domperidone
Probiotic should also be added for relief from your symptoms.
I hope this is helpful to you.
