I’ve had watery diahrrea, sulphur burps, stomach pain and extreme nausea (but no actual vomiting) for 4/52 weeks now. I’ve had a stool test and no infection noted. I have diverticula disease but no flare ups in 3+ years. The sulphur gas is very frequent and very potent. The stomach pain is in the exact centre of abdomen (this is as well as a constant pain in the upper left side of abdomen that is front to back (sometimes tender to touch) which I’ve had for 1yr+)
