Oh my goodness, it went through my household about a month ago. It was AWFUL! I had D more than I have ever had with Crohn's! I threw up a few times as well. And the stomach pains were unbelievable! I took a few Norco to help with the stomach pain. The stomach pains hurt so bad I was moaning like a baby!
Mine lasted for probably 4-5 days. Once the D was gone, I had awful, AWFUL gas that lasted for about another 4-5 days.
My son ended up getting it twice--I didn't think that was possible, but the second go around, I called his pediatrician and they said you can get the same thing twice.
I sure hope you feel better soon because it is nasty bug going around and having that on top of Crohn's REALLY bites!
I had the stomach flu 20 days ago, it lasted 2 days I wasn't throwing up but the nausea was awful, terrible D, headache, low fever, loss of apetite, and sleeping all the time.
