Smelly gas

Hi there, Has anyone found any answers to obnoxious smelly gas? I'm going crazy. I've had every test mentioned including colonoscopy and the test for upper colon, lower colon and stomach. Seems doctors can't figure it out. No stomach pain just bloated and constipation then of course, diarrhea eventually by goimg around the hard stools. Doctor has me off of all lactose for over 2 weeks now. I'm on fibre, laxatives and a pro-biotic. Did a salt water cleanse over a week ago. Blood test shows I'm not gluten allergic. Off all spicy foods, following the fodmap. Advice please. Oh, I tried tumeric capsules and peppermint oil in veggie capsules.

I don't think this is a problem with your nose!!- maybe try an IBS discussion group 

I was thinking the same thing....

Sorry and thanks.
