my daughter has theses episodes that end her up in the emergency room. It always starts the same way. First sulfur odor burps for hours, then violent vomiting and diarrhea. These episodes last about 6hrs. She is given pain meds for the unbearable pain, and an Iv to hydrate her. This has been going on for over a year with these episodes going on every 3 or 4 months until now they have been monthly, and this time its been 2 weeks.They have done blood work and scopes with the results being all normal. I dont know what to do. Do youhave any ideas that we could try? Thanks for your time and help.
