I believe it would depend on how fragile the mucosal layer is and how much inflammation. As well...you're on an antiinflammatory medication, which could account for some of the confusing symptoms.
UC does come in progression of inflammation, and many of us don't seek professional care until symptoms are quite obvious.
You should make sure you request rectal meds in conjunction with the Lialda after your scope...maybe that will help keep you off pred in the future (which is a good thing).

My doc's logic.. "TREAT (FROM)BOTH ENDS" worth it !!!
