just been googleing it and this is what someone said they had as a symptom
8) Farting. the silent but deadly type with heat!! haha!!! Seriously, I could probably torch something with the amount that I was pootin' away. And I NEVER pass gas in front of my husband so it was so embarassing. It wasn't like I could leave the room and come back after a light wind. The smell would waft back in with me and I couldn't hide it. My husband was gentleman enough to let me keep my dignity intact and spare me any jokes, but I still felt like 'plugging it' when he lit incense to mask the smell. I know, tmi, but hey, you asked.
PMSL I have been 'farting' recently OMG cant believe Im admitting this but its been for the past few days and I dont usually, well not in public but Iv been extremely gassy. im starting to get my hopes up now, god damn google!
