Hiya! I feel for you! It seems that the more nervous or 'stressed' one gets about something the more likely it is to happen.
Don't underestimate how this worrying will effect your CD! Stress is a major player. I would start by trying to be a bit more positive and bit more hopeful. Tell yourself it won't make a difference rather than worrying about getting worse. I too get caught in the trap, when I get a few gut pains or some LBM I can start to worry 'is this a flare' but over the years I have learned that I can think a flare into existence.
I know we are not all the same, but stress effects us all. And dealing with it better will improve your overall health. As cheesy as this is and as much as it pains me to say it "try to look on the bright side" Positive words can overcome worry and doubt.
So here it goes: I really think that you will be able to cope and that with some pain meds and with the forthcoming surgery you will soon be off the Pred and be able to face the day with new confidence. i believe in you! {{{{{{{{{{{{MAG102886}}}}}}}}}}}}}
Don't worry about asking for pain meds, it is normal and par for the course.
