hello, my 12 year old son has been Dx with CRMO by MRI.  All blood tests were normal (mild iron deficient anemia).  Normal CRP. The doctor put him on Indomethacin 75 mg a day and ordered calprotectin to check for possible CRMO since he has been having very vague GI issues.  His calprotectin came back elevated as 300, I don't know what to make out of it.  I put him on gf and dairy free diet and his GI issues are gone. I am thinking that maybe Indomethacin has elevated that number?  Anyone has experience with that? Or maybe if you have CRMO the number is elevated?  I also took him off Indomethacin and give him Advil daily (once a day).  It keeps him symptom free.  I don't understand why I need to give him stronger pain killers if Advil controls it?
