From your description, it appears your Crohn's is not in remission.
Fistula is active and the black stool
is suggestive of slow bleeding.
I know you have been on Immuran for sometime now and I feel
that has not been effective at this stage. What you need is a complete
re-assessment with additional x-rays or endoscopy
, blood work.
You may do well on Infliximab
) , but you have to be under
close supervision. Drug is given as an infusion (IV) at a center or doctors
office at regular intervals. You need to see a gastroenterologist for
evaluation and change in therapy.
I wish you the very best.
