Hi. Thanks for your query. Noted the history and understood the concerns. It is possible that the procedure of anesthesia can cause minimal trauma during intubation and thus cause throat pain which usually settles within a few days. But the feeling of burping without actually being able to do one may be due to gastroenteritis as you also have developed bloating and indigestion. This can be due to the antibiotics and other medications. Hence I would advise you the following in such a situation: Continue Prilosec as before. Take antacids and see the results. You need something like Domperidone or Reglan for the sensation that you have. Get stool test done and if there is any evidence of any intestinal infection your Doctor would prescribe you additional treatment with an appropriate antibiotic, symptomatic and supportive management.
