Summary

The goal of this clinical trial is to learn about the effect of a sphenopalatine ganglion (SPG) block in anxious patients at electronic dance music festivals. The main question is:

\- Is an SPG block useful in reducing anxiety, in comparison to placebo?

Participants will have lidocaine-soaked cotton tip applicator placed inside each nare for 10-minutes, or have a saline-soaked cotton tip applicator placed inside each nare for 10-minutes.

Researchers compare the lidocaine-soaked intervention (SPG block) with the saline-soaked intervention (placebo) to see if it reduces anxiety in patients presenting at electronic dance music festivals with anxiety.
