Lila,
I just had a sticture removed from the colon which had shown significant narrowing and inflammation over the last two years. I also have had some mild Crohn's in the TI. Neither of this has given me diarrhea or pain. I had the stricture in colon removed to prevent future problems and no medication was going to take that away as I had had tests showing deep scar tissue.
Now there is the question as how to treat the Crohn's. GI is now inclined to treat the disease and not the symptoms. I am having a small bowel ultrasound done and GI did mention Humira. I would really question this if I am not experiencing any symptoms. Meanwhile I am on Methotrexate and I hope that it does the job. I never wanted to be on these drugs long term but am slowly realizing maybe it is for the best to be on something.
Wolfie is facing the similar situation with Humira and having a CT scan on Monday. I am sure you will hear from him and I will be interested in other people's responses as well.
Know it is a very hard decision to make and good luck on your next TB test.
