Hey Daniel, welcome to the forum!
Are you on Remicade now? What medication/treatment are you on except the prednisone? Have you had 5-ASA, or immunosupressive therapy?
As others have said, there are a few tricks you can try, including:
-Avoiding fiber, which means no wholegrain/wheat bread or pasta, no uncooked fruits or vegetables
-Avoiding lactose
-Avoiding gluten
-Avoiding irritants such as caffeine and alcohol
-Medical marijuana
These are palliative though, but they can make a big difference. As Jim says, surgery might be an option for you if your disease has reached a point you consider too debilitating and you're fed up of dealing with the flares.
Has you doctor discussed the long-term plan when it comes to your UC?
