I have foul smelling gas, feel bloated and have abdominal that pain comes and goes. what are my next steps?

See a GI doctor: These types of symptoms can be part of irritable bowel syndrome, crohn disease, inflammatory bowel disease, infections, etc. Diarrhea, constipation, blood in the stool, cramping, etc, are all things you should be prepared to tell the GI doctor -- who will probably do a colonoscopy/endoscopy, depending on your age, and other symptoms.
