Efficacy of PENNSAID® for Pain Management in the Emergency Department
The primary objective of this study is to compare the pain relieving effect and speed of onset of PENNSAID to that of standard oral diclofenac under double blind conditions using a growth curve approach to pain measurement. The investigators will test the hypothesis that PENNSAID will provide more rapid pain relief than oral diclofenac during the ED visit. The secondary goal of the proposed work is to discover and model the onset and course of pain relief during the emergency department (ED) visit.

Active Pennsaid and oral placebo
active treatment with PENNSAID and oral placebo. Subjects will apply 40 drops of Pennsaid to the affected ankle joint once, and will take a single placebo pill.
Active Comparator: Oral Diclofenac
Oral diclofenac and placebo lotion (2.3% DMSO solution)
Drug: Diclofenac hydroxyethylpyrrolidine
active treatment oral Diclofenac and PENNSAID placebo. Patients will take a single 50mg dose of oral diclofenac and will apply 40 drops of placebo lotion (2.3% DMSO) to the affected ankle once.
