I don't know anything about crohn's meds, can they cause a mass? If not why wouldn't he send you for a scan to see what the mass was? Maybe it's time to seek new drs? I've had 5 GI drs and I thought it was 5 urologist until I recounted and its been 6 of them until I finally have competent, compassionate drs. There are great ones out there, you unfortunately have to keep searching until you find them.
I hope everything is okay and you feel better soon,
