i am 23 yo. i have digestive problems since 4 or 5 years now. i received iron transfusion when i was 18 due to severe anemia and the doctor prescribed me amoxicillin and flagyl which i did not continue for more than 3 days due to severe side effects where i would throw up mouthfuls of thick white foam every 10 min. every time i eat or drink, i release a long burp that doesn t sound anything like the usual burps. it feels like something (maybe air) is rising with difficulty, from deep within. i often hear sloshing in my upper abdomen regardless of the fact whether im hungry or not. i dont feel hungry all that much. i have been diagnosed twice for worms but i never saw any in my stool. sometimes i throw up thick white foam, especially when i eat fruits. i recently got my lftr and cr and us of upper abdomen, but the all the reports are normal.
