Well, I have only had two outbreaks in the last four years. Both occurred with diagnosed yeast infections, so, like you, it was hard to tell because I already had uncomfortable things going on. I didn't really notice a tingling until after I started having symptoms (ithing,tears), so I don't know how
I will know either. Hopefully I won't have anymore outbreaks because many people with Type 1 only have a few outbreaks and then never have one again. That would be nice, wouldn't it?!?!
