Thanks for the tips. Good idea to check with the insurance company, so I will do that. I don't want my decision to be only based off of cost, but it is a consideration.
As for the flex sig... I wasn't scheduled for one. I went in to see him because nothing seems to be working, and he said he could do it right there and then, that it would be a quick look. So I am grateful that he was able to do it right then and not have to schedule me for another day. It was only about 2 minutes, because he didn't do the full thing, just needed to get a quick look to confirm the activity. And honestly, if I wasn't flaring, it probably wouldn't have been too terrible. Having your colon inflated when you are already uncomfortable just is no pleasantry!
For those that have done Remicade/Humira and had success... how long was it before you started noticing improvement?
