My 95 year old mum has been diagnosed with this. She lives in Australia. The symptoms are a lack of feeling in her hands and feet, but she can also suffer bouts of extreme pain in them. It is apparently untreatable and incurable - although she has experienced a remarkable improvement in the last six months. I have never heard of this condition before - is it called something else in UK? or is it a releatively newly discovered condition? Does anyone have any experience of this?
