You sure sound like you _know_ a lot about EC. :-) Just because we have the same or very similar symptoms, that doesn't mean we have to have the same condition/cause. What makes you so sure that it is the case?
I do agree that there is no evidence that patients that might have gotten their EC due to trauma need to do anything different than patients that got it out of the blue. But, maybe some "out of the blue" patients have some unknown underlying cause that they have to get rid of first.
