Does anyone have experience with cyclic vomiting syndrome, and can illness trigger a flare up? My 9yo always vomits with every illness, not just a tummy bug. Like now for example, she started with a cold and earache, and has now been vomiting every hour for the last 12 hours. This always happens, surely she doesn’t catch a tummy bug on top of a cold every single time? I was reading about cyclic vomiting syndrome and it got me thinking.
