kasburn, you're correct. the terms should be more specific: Right front lower quadrant; left front lower quadrant. After looking at the pictures of the colon, you can see exactly where the ileum is and identify the point of pain pretty accurately.
Interesting, I didn't know that Entocort only works on the terminal lieum, I thought that it was an anti-inflammatory. I guess I need to discuss the general colon inflammation that he diagnosed with him.
