Summary

This study tests whether stimulating the vagus nerve through the ear can reduce pain after anal or rectal surgery. Fifty adults will use a small device twice daily for two weeks before and after surgery. Researchers will track pain levels and painkiller use to see if this simple, non-invasive approach is feasible and helpful.
