My pwp has suffered from painful muscle rigidity in his back for several years, and we found nothing to give relief. It has been much worse this year. We started on a gluten-free diet about a month ago, for an unrelated reason, and found that his back isn't going into the horrific spasms it has been. It has been about a month now with little back pain... with one exception...

He ate a sandwich on regular bread one afternoon. That night the rigidity/spasms and pain were back. We are staying away from gluten now!
