This one apparently isn't caused by trauma, and they aren't sure why it happens. I've had enough trauma through military service to give me PTSD and the symptoms are very different and debilitating. They have been worse since I haven't been working because I think the old work stresses suppressed the PTSD.

This is just one of those oddball syndromes that can happen to anyone, but it has a great name doesn't it. I just hope I never get it again, it was spooky as hell...
