14 May 2019	New citation required and conclusions have changed	We updated the searches. We included one new study, Hayward 2017, and excluded one new clinical study (Chen 2018). Corticosteroids increased the likelihood of complete resolution of pain at 24 hours by 2.4 times, and at 48 hours by 1.5 times. Corticosteroids reduced pain (assessed by visual analogue scores) by an additional 10.6% at 24 hours. Corticosteroids reduced the mean time to onset of pain relief and the mean time to complete resolution of pain by 6 and 11.6 hours, respectively, although significant heterogeneity was present.
