What medicine does is primarily treat the end product of the inflammation with symptom suppressors rather than look to the source of the inflammation, which in this case, appeared to be excessive worry brought on by too much success! Of course it's confusing when we look at the body as if each part were totally separate. We look at nouns instead of verbs, organs instead of processes. When we think of process, we think of inflammation affecting multiple organs in a variety of ways that are as individual as the person herself.
The hard sell is to convince people that their bodies respond to the events of their lives. We have been trained that an impenetrable wall separates body from life. So long as we believe this, our symptoms are mysterious and undiagnosable.
