<s>[INST] I have recently starting having chest burp/gurgling noises when I breath in deep and my chest feels more constricted than normal. I was on penicillin recently for a bad cough and sinus. Never had this sensation before and starting to worry me. What can I do? [/INST] Thanks for your question on Chat Doctor. I can understand your concern. Penicillin is an antibiotic. This can cause gastritis and gastritis in turn causes all your symptoms. So better to take pantoprazole and levosulperide combination on empty stomach twice daily. Avoid stress and tension. Avoid hot and spicy food. Avoid junk food. Avoid large meals, instead take frequent small meals. Go for walking after meals.Don't worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
