<qa>  What is the standard pain scale used in our Pediatric ED?To assess pain, the investigators will use the standard pain scale that is currently used in our Pediatric ED in order to minimize the need to re-train any of our staff with a different pain scale. The scale incorporates the Numerical rating scale 0-10 scale; NRS and the Wong-Baker faces pain scale 6 faces corresponding to 0,2,4,6,8,10; WBS. While prior studies have used different pain scales, primarily the visual analog scale VAS, the scales that the investigator currently use have been validated in children in 2009.
