Hello! Thanks for putting your query in HCM. I am a Gastroenterologist (DM).
Some of the antibiotics may cause gastritis
which leads to the above symptoms you have mentioned. Either change your antibiotics or may take a proton pump
inhibitor like rabeprazole
and a prokinetic agent like domperidone
I hope I have answered your query and this will help you. Remain in touch and get-well soon
