Women scheduled for urodynamic testing at the Los Angeles County University of Southern California (LAC+USC) Urogynecology clinic will be invited to participate. Participants who meet inclusion criteria will be randomized to the aromatherapy or the placebo group after informed consent is obtained and immediately before undergoing multichannel urodynamics. Sequentially numbered sealed opaque envelopes containing the identity of the study arm will be used for randomization. The urogynecology clinic nurse will prepare the aromatherapy versus distilled water on the paper towel that the patient is routinely given to hold over their mouths when asked to cough during the procedure; two drops of each will be utilized. Before the physician comes in, the nurse will ask the participant to take a deep breath while holding the towel 3 inches from her face and will instruct the participant to continue to take normal breaths subsequently. It will not be possible to blind the participants or the examiner to the assigned group since the lavender oil will have a different scent than the placebo. However, the use of distilled water on the towel will allow the possibility that the deep breathing accompanying the instruction may have an effect on reported pain and anxiety.
