Interesting topic! I too have a sciatica but I got mine moving something the wrong way. The orthodopedic I saw at the time said I was in the typical category (female over 30). As far as celiac I know all my aches and pains flare up when I'm glutened, but I just figured it was the immune system hitting the weakest areas.
Yep! And check your vitamin panel. My doc. Said it was rare to have constipation than diarrhea but it didn't change the diagnosis. Your bloodwork and biopsy confirms your disease. I'm finding all of us react in different ways.
