Name Time Method Main Objective: To study the reversal of established hyperalgesia.<br>The main outcome variable will be: area of pin prick hyperalgesia.;Primary end point(s): Area of pin prick hyperalgesia 6 hours after stop of IMP;Secondary Objective: To study the reversal effect on additional outcome variables for mechanical hyperalgesia will be: stimulus-response (SR)-function to a set of modified rigid von Frey filaments (8 -512 mN), area of dynamic allodynia to brush and SR-function to dynamic mechanical stimuli. <br>Pain immediately after injection and heat pain threshold within the area of mechanical hyperalgesia will serve as additional outcome variables.<br>
