Study Summary

This study will compare the current standard-of-care pain treatment regimen options that are available to patients who undergo gender-affirming surgery. The purpose of this research is to determine if any of these options are more (versus less) effective than the others to manage surgery related pain, after surgery.

Primary Outcome

Anterior and posterior illustrations of the body, with pre-defined areas involved in surgery that may be circled, will be used to define pain location. Pain scores for each circled area will be measured on a Likert-scale between 0-10, with 0 indicating no pain and 10 indicating the worst pain experienced in respondent's life.
