HIDA scan- sick afterwards?

Had a HIDA scan this morning. Stopped for McDonalds on the way home and ate half an egg and cheese McGriddle. About ten minutes later I immediately got sick with severe nausea and diarrhea. I know McDonalds isn’t good but I’ve never had a reaction like that. The nurse didn’t give me any restrictions but is this likely from the CCK they gave me? Has this happened to anyone else? Called into my drs and left them a message of course.
