Average pain reduction effects of Neuragen PN ^® and the placebo, represented by the Visual Analog Scale (VAS) where 0 indicates no pain and 10 indicates maximal or severe pain. The vertical whiskers on each data point represent the standard error about that point. Pre pain level was measured 30 minutes (hour 0) before treatment application and post pain was measured 30 minutes (hour 1) after treatment application and every hour thereafter (hour 2 - 9), up to 8 hours. There was a pain reduction (p < .05) for both treatments up to hour 9. Neuragen PN^® led to more pain reduction than the pacebo during the first 4 hours after treatment application
