Rant-possibly time to give up humira

So far this year I've abnormal paps, root canal gone bad and retreatment infection, kidney stones, and now I think the retreated tooth is infected again because my ear is killing me and my reg doc says its not infected. I'm out of time at work and out of money for uncovered med expenses. My GI suggested last year that I may have to quit the humira if I keep having infections and well . . . But here's the thing, then what do I take? Can we crohnies really go back to regular meds after a biologic?
