Hello. I was diagnosed with PPMS two and a half years ago.i had my annual (a year and a half) appointment with my consultant last week. He thinks I have a rotated facet joint in my lower back and that is contributing to mobility problems. He says the part concerned is not somewhere MS attacks. I'm going to have an MRI and then hopefully an operation - key-hole or otherwise. I know it will do nothing for my MS but my hope is that it might in some way improve things overall. Was just wondering if anyone had a similar experience. Thanks.
