Burping the taste of rotting popcorn

[Kattybear16]

My burps have been tasting like popcorn gone bad, even though I haven’t had popcorn in awhile and these burps have been going on for almost a month now.. I have tried a bunch of different over the counter things and even ate some ginger and nothing has helped. What do I do? I have even been making sure to drink water to try and flush the taste out but still nothing has worked. What do I do? Do I need to see a doctor? There is also a stomach virus going around, I am wondering if the burping is part of it because I have a few symptoms of the stomach virus.. oh also sometimes when the burps get really bed they seem to bring heartburn with them. I am seriously at a loss here… please help
