Joma,
That is exactly what I do to stop a flare before it gets out of control. The minute my stomach starts gurgling or I have an extra trip or two to the bathroom, or Im more gassy than usual then Im headed for a flare.
I start the hycort enemas and cortifoam. I use cortifoam during the day and hycort at night and things usually calm down within a few days to a couple weeks. I start and stop the enemas all the time.
By doing this I have not had a major flare in many years. You really have to listen to your body and act quickly. Dont wait for the mucus and blood because by then its too late. It will take longer to get things back to normal.
I also eliminate foods when the gurling starts. Lettuce for one is a killer for me when symptoms start. Bread is another.
I also increase the probiotics at that point.
