Psyllium made my eyes threaten to flare, too. Thanks for the explanation why!

I have Reiter's Syndrome, an HLA-B27 disease similar to AS. Diagnosed 2008. I used Humira and methotrexate until 2012, when I was diagnosed with leiomyosarcoma and given a hysterectomy and a 26% chance of 5-year survival. Cancer-free ever since I stopped taking Humira and methotrexate; trying to trust medicine again. In a mobility scooter since 2013 with joint pain and disease-related stress fractures. Uveitis. Eyes and joints flare whenever I stray from a severely limited diet (NSD+).
