Hi, may I answer your health queries right now ? Please type your query here...Recently my son and I have gotten sick, with what we thought was a gastro bug. My mother also has it. She had it for three days. She thought it had gone away, but this morning it came back. My question is..Can you have sulfur burps, diarrhea, and a lot of foul smelling flatulence without it being giardia, and have it be just some weird bug???
