Summary

This study tests whether a gentle electrical stimulation on the ear (called taVNS) can reduce joint and muscle pain caused by aromatase inhibitors, a common breast cancer treatment. 216 women with hormone-positive breast cancer will receive either real or sham stimulation daily for 28 days. Researchers will track pain levels, mood, quality of life, and side effects over 6 months.
