About six months ago, my husband had his first ever sulfur burps. It went away after a couple days but he s been periodically getting them again. They smell NASTY, just like rotten eggs, even though he has not eaten eggs. The last couple days he s been burping sulfur again, has had terrible diarrhea, and has been complaining of not feeling right . Do you believe this is just some sort of intestinal virus or does it seem like something more serious that he should see a doctor for? We do not have a lot of money so we are worried to pay $200 for him to go to the doctor if it s nothing to worry about! Thanks so much
