Whether or not you should be on medication is a tough call. You obviously haven't had severe disease and haven't needed surgery, but you do have some active disease. Eventually that could lead to problems necessitating surgery. Or it might not. Too hard to know. It might be years, even decades, before you'd need surgery, if at all.
Your mild disease might have been in remission, or it might have been 'smoldering' along at a low level.
So do you take meds to prevent *maybe* needing surgery down the line?
Are you symptomatic now from the acute ileitis? If so, maybe Entocort could help with that.
As for taking stronger meds as maintenance, ask yourself what your quality of life is like? Is it good now without meds? If your symptoms aren't bad at all, it's hard to justify costly meds that *might* have lots of side effects. Are you terrified of a possible future surgery? Are you wanting to do *anything* to prevent surgery? If so, go on meds.
If you're doing ok now, consider just a watch-and-wait approach, meaning you see the doctor every year and get a scope or MRI/CT every year or every other year. That way you can keep on top of things. If they start to show problems, you can get on meds. If you continue to cruise along without much significant inflammation and permanent damage, then you can stay off meds.
