Pain wind-up

Pain wind-up is the perceived increase in pain intensity over time when a given stimulus is delivered repeatedly above a critical rate. It is caused by repeated stimulation of group C peripheral nerve fibers, leading to progressively increasing electrical response in the corresponding spinal cord (posterior horn) neurons.[1] [2]
