Maybe it's time to seriously think about
You can't afford Remicade (been there, couldn't afford Humira), your fistula will not going to get better without drugs, and you're incontinent and depressed.
Maybe it's time to get an ostomy, temporary or permanent depending on what your surgeon thinks, to divert everything, give your fistula a chance to heal, and at least not worry about
leaking through it, and possibly put you in remission for a couple/few (or more) years.
I know surgery is a last resort, but you sound like you've had it with medications as treatment.
If you need someone to talk to, give me a shout. My e mail is in the box to the left.
25+years diagnosed with CD.
Numerous surgeries, permanent ostomy, adverse reactions to Remicade, still on Prednisone (my worst enemy), Finally had another surgery hoping for a long remission.
