Hi, My son was diagnosed with Lymphocytic Colitis, which is related to Collagenous Colitis. There's not much research, no good information that pertains to our situation. Have you found any useful sites? Most of what I see is on UC or Crohn's, which is not the same thing. Also, can I ask how old you are? My son is 6 y.o., which is from what I hear unusual. My main concern is prognosis for the long run for him, which is not very clear to me.
