HI Ronroush7, i have had crohn's since 1990, and i still get the cold flashes and the hot sweats, the hot flashes are the worse. My bedroom is always cold about 17 degress C. i have to have it cold or i can't get any sleep. but, funny in the day time i am cold most of the time. so , yeah i have cold and hot flashes. it sucks, but i guess it comes along with this IBD.
