I have no idea what a DX is.

My pain issues are directly tied to the Post Traumatic Stress Disorder element of my PCS... the chronic pain I experience basically runs a clear path from the left/top side of my head (where the impact occurred) down through my neck, back, liver, and right leg, all the way down to my ankle - it's like a little trauma tornado ripped through my body and left a trail of destruction in its wake.
