Summary

This study tests whether a painkiller called suzetrigine can reduce pain after breast surgery (not mastectomy). About 120 adults will take the drug along with a nerve block. Their pain levels will be compared to past patients who had standard care. The goal is to see if this combination provides better pain relief.
