Summary

This study looks at two types of nerve blocks given before mastectomy to see which one better prevents chronic pain. About 132 adults having a mastectomy will be randomly assigned to receive either an erector spinae block or a paravertebral block. Researchers will track pain, opioid use, and emotional well-being for 3 months after surgery.
