Patients presenting with painful procedures in the Emergency Department (ED) have been shown to frequently have inadequate pain management. The incision and drainage (I&D) of an abscess is a common procedure that is viewed by many emergency physicians as only requiring a localized anesthetic for pain management. However, it has been documented in previous research that there can be disconnect between what emergency medicine physicians interpret as painful and what patients experience as pain. A trial will be conducted to focus on use of intramuscular (IM) Fentanyl as an intervention to help alleviate pain associated with the incision and drainage of an abscess. This is a procedure that rarely receives systemic opioids.
