If your throat pain is like heartburn (acidic burning feeling), and if you burp and have burning stomach, this is probably from H. pylori infectionof the stomach. Diagnosis is with the breath test, treatment is with antibiotics.
I also have the same stomach bloating symptoms which makes me look pregnant too. If you take a look at my pictures I have linked to my profile you can see the dramatic difference between the way my stomach looks before and after. After dealing with this for over 3 and a half years no medications have ever even came close to helping with the stomach bloating. I've also felt the discomfort on my rib cage when my stomach gets bloated. It's just too much pressure on it. Is your stomach permanently bloated or is it after you eat or drink certain (or any) food? And how frequent does it bloat after eating?
My stomach is permanently bloated and when I eat it seems to grow,,,,,my stomach is really hard above the belly botton
