The long-term side effects of steroids are nasty, so your doctor is hesitant to use them too much - that's great, actually! so many docs seem to push prednisone. (Because, as you experienced, it can be a very good medication.)
I was on pred when I was first diagnosed, and I had trouble getting off it - about 2 years. My symptoms kept coming back when I tried to taper off.
So, since then, when I've had a flare that won't respond to the oral and rectal 5-ASAs (as you've been taking) I have asked for steroid enemas. They've done well for me, and have a lot less side effects than the oral steroids. Even when I was flaring well up into the transverse colon, the steroid enemas eventually took care of it.
As with anything else, they don't do the trick for everyone, but if you have not tried them, maybe ask your doc what he thinks of trying them?
There is also rectal steroid foam available... I used that some, years back, but generally my issues go further than that can reach (I have pan colitis.)
