Anyone know about this? Mum was diagnosed with this a few years ago and barely anything on the internet about 12th rib syndrome (nerve trapped inside 12th rib/floating rib). Nerve block injections not worked. She is taking lots of medication (pregabalin, oromorph etc) physio not making any difference. I don't even know where to look for help any more?? I just can't believe that there is nothing that will stop the pain???
