Primary Outcome Measures :
  1. Analysis of Total Pain Relief (TOTPAR) Over 0 to 12 Hours (TOTPAR-12) After Time 0 [ Time Frame: Over 0 to 12 Hours ]

    Total pain relief as computed as a time-weighted sum of individual patient pain relief scores at each timepoint from 0-12 hours.

    Values for TOTPAR are measured from 0 to 4 on the Pain Relief Scale 0 None Min; 1 A little; 2 Some; 3 A lot; 4 Complete Max
