Chronic Pain

Sitting here feeling tired and generally unpleasant and unfocused and not really realizing why, I felt a twinge in my wrist and an epiphany. Chronic pain doesn't just manifest as pain in the affected area, does it? In fact, you can experience those "secondary symptoms" while not consciously experiencing the primary sensation of pain? I think this may explain much which was unclear to me in the past...

Comments welcome.
