Hi,
Gut infection is likely.
Stool test may be done for evaluation.
Take probiotic supplements, prilosec and simethicone for relief.
If gut infection is found positive, depending on the type of infection, you may have to take other medications as well to eradicate it.
I was tested for h pylori came back fine had 3 stool smaples all came back fine still get burning in stomach and now getting headaches on right side and feels like burning and ear clogging up help.
