what should I do?

Since last week I have been suffering from constant stomach related problem like growling(frequent), bloating, mild pain and excessive burping. Excessive burping is what causing me to freak out. Its just that I have constant wind trapped feeling in chest and I have to force out. Burping is strong and noise like I have some infinite air

I agree, you've got a lot of gas. You can try gas x, peppermint oil, or ginger teas. Try to exercise as well. If your gas increase you may have an overgrowth of bacteria somewhere in the colon. If so, an antibiotic might be indicated. Try to decrease your yeast producing foods as well. I hope that you get better soon.
