Phase II: Patient Follow-up Subjects will be followed closely with weekly phone calls from the research assistant for the first four weeks of the trial. During these events, the PHQ-9 will be administered and questions will be asked regarding adverse events and side effects. After this, subjects will be telephoned bi-weekly for the duration of the trial asking the same questions. In addition, at one month and three months after the initiation of the research drug, during the telephone interview, subjects will be administered four questionnaires: the SNOT-20, SF-12, PHQ-9, and the SCL-20. Chronic sinusitis subjects and facial pain subjects will complete identical forms as there is common symptom crossover.
