I saw a mention on another thread suggesting that back ache and IBD can be connected, and just wondered if anybody know more about this topic? I get agonising back ache at times but it hadn't really occurred to me that it could be anything to do with IBD. I've lost loads of weight since the IBD problems and the weight loss has done wonders for knee and hip pain problems (every cloud has a silver lining and all that) but nothing for my back.
