Could be anything, and not necessarily ileo or IBD related. I know that's the obvious place to start, but keep in mind that we all still can get muscle aches, bruises, strains, etc.!
What have you tried to treat it? Does an anti-inflammatory help at all?
Who is doing your scope on Tuesday? If it's your doc, it's worth mentioning it if it is still bothering you then. He/she will probably tell you to consult with your GP if it continues, but it doesn't hurt to ask.
