Puppylover, I never had that problem with Crohn's. You can have some weird things happen, though, and this might be one of them. I hope she had seen her doctor about this. Maybe she is retaining too much fluid. I know when I have any swelling, I can sometimes get little red dots on my skin and it itches but it really is from the swelling.
Let us know what she finds out. I'm curious. I'm sorry this is late but I missed this post!
