Abstract
This is the case history of an allergic teacher who developed variable loss of power and co-ordination in her legs following small operations requiring anaesthetics, which later developed into severe multiple chemical sensitivity while she was working in a new building, so that she needed a wheelchair. When full investigation in a teaching hospital failed to find an explanation, she was referred for an allergy opinion, admitted to the Airedale Allergy Centre (AAC), an environmentally-controlled unit, and her symptoms cleared during a therapeutic fast. The environmental factors provoking her symptoms were identified and her management consisted of avoidance and low-dose desensitization. In the 11 years since then she has managed to keep well with care and takes 12-mile walks.
