As you know, the primary tenet in the EMDR work is that experiential contributors to pathology can be successfully processed--and can therefore be alleviated. The notion that there are psychological contributors to somatic complains is one that needs be explored in regards to a variety of problems. Please consider writing up a detailed description of the the case for journal publication in order to inspire future detailed study. It sounds like your observations can potentially contribute to to the alleviation of a massive amount of suffering. Don't underestimate the importance of your observation and the dissemination of these findings.
