Hi i have a sour stomach and bloating since sept 1. I tried zantac for 12 days but still have the sypmtom. I feel like I want to vomit but what came out was just a clear saliva and air. I also want to burp but sometimes it wont come out and ended up boating because i can hardly fart. Every meal i feel bloated and always belch. I gried omeprazole 14 days but still have the symptom. i also have a slight sensation at the epigastrium when i bend. Pls help.
