My grown son has these symptoms: sulphuric smelling and tasting belch, bloating, fatique, diarrhea one day, constipation the next, headaches, severe pains in stomach, and tired. He has had two bad bouts with this within a 6 month period. Ended up staying in the hospital where a series of tests were done. Negative on gallbladder, pancreas, and appendix. Doctors relieved the initial problem with IVs of fluid, toradol for pain, GI cocktail for the stomach problems. Bloodwork showed slight elevation of WBC but nothing major. Any ideas?
