Stomach flu (I have UC)

My symptoms started two weeks ago today. It started with me feeling totally fine and then within an hour I had diarrhea three times in two hours. Over the course of the first day I developed nausea, chills and body aches. Never had a fever. The next few days were better, with having mild diarrhea (max 1-2 times per day) and tummy upset. After three days felt pretty normal and decided to have some real food... bruschetta and a salad. Big mistake. Symptoms pretty much started over the next day. No chills or body aches times time, just nausea upset tummy and diarrhea. After a few days, felt good again so ate grilled cheese and fries one night and bruschetta again the next.. apparently not the best decision. That was about a week ago. I've been eating very bland for a week and it just seems like every time I try to add something different, the virus knocks me back down. I have a call into the doctor but I'm just wanting to hear others experiences with this. I have IBD so it makes sense that it might take me longer to recover, but Jesus! The longer it goes on the more I'm hoping it's not a flare of my UC... I welcome all comments and/or suggestions.

Thanks!

Believe me, I know it's not influenza. Even my primary calls it stomach flu. Regardless of what's it's called, my symptoms point to norovirus. Can stool samples assess whether it's gastro bug or if my UC is flaring? I just had my scope in November and it was the best it's ever looked. Didn't know if an increased fecal calprotectin number could also be indicative of gastro bug or if it would just show elevated and it could be either?

My entire family had it. I believe I caught it while out of town for the holidays. I used to take vsl ds but my insurance stopped covering it and I had to quit due to it being 1000 bucks/month. I currently take Florastor.

Any other thoughts on why/if it's common for people with UC to take longer to recover? Just don't know why it's been so long.
