Leah,
I replied to your other post, but just want to reassure you again. When Crohn's has been allowed to take hold, it really needs to be treated aggressively. Entecort can be a good drug, but you really should have been on Prednisone to really combat the disease.
Again, try to stay positive. Give the Remicade a chance. You should also ask your GI to do some follow-up diagnostics to see how things look. Preferably an MRE, (MRI).
Good luck, things WILL get better. Keep posting. You'll get alot of good advice here.
