Sacroiliitis: Natural Remedies That Can Alleviate Pain

Hi there, I'm looking into natural remedies for Sacroillitis. Does anyone know of any? So far, I've tried a massage, the chiropractor, yoga, youtube videos for stretches. It doesn't seem to be helping. I am going to try acupuncture and foot reflexology afterwards. I imagine physio is just stretching exercises, I will still try it just in case. After all this, I still feel intense throbbing up my spine, around my tailbone, my buttocks and shoots down my leg. This is making it really hard to walk. Any advice of herbal medicine or what you may have done yourself would be greatly appreciated. Many thanks, Melody Z

P.S. I should mention that I have been diagnosed with Ulcerative Colitis. I am currently on Prednisone and asacol. I hear that gluten free diet helps with Sacroillitis relief as well.. thoughts?
