While in the hospital, subjects will be provided with a Patient Diary and will use the diary to record all scheduled and unscheduled VAS scores. For all scheduled assessments and unscheduled assessments in the hospital, subjects will assess, "How much pain are you experiencing right now" and a vertical mark will be placed on the VAS line to indicate the level of pain experienced at the time of assessment. If a subject is discharged prior to a scheduled VAS assessment, a member of the study site staff will telephone the subject to remind her to complete the scheduled VAS assessment at the scheduled time and to record the assessment in the Patient Diary.
