Would anyone out there be willing to share how difficult is it to use the Budesonide foam for a young adult? I'm asking about logistics at this point. Is it uncomfortable? Is it hard to figure out how to do? I understand that many people believe that it doesn't go deep enough to touch Crohn's, but our doctor (head of an IBD center) actually brought it up, his Crohn's is affecting the tail end of his colon, and my young adult son seems open to the idea, so I'm just wondering if anyone has any warnings or suggestions about it purely in terms of the mechanics of it. Thank you.
