People who get serious spinal cord injuries have to adjust to a lot. That may be why, in the first year after their injuries, they are at serious risk for a potentially fatal condition called autonomic dysreflexia. Autonomic dysreflexia shows that the body can take itself down if its signals are ignored.
First signs are profuse sweating above your level of injury. Then chills with goose bumps, and very cold clammy skin. If its something like a clogged tube, that can be very dangerous. The bladder unable to empty itself makes the autonomic dysreflexic symptoms worsen.
