Nerve block rebound pain mystery probed in healthy volunteers
NCT ID NCT06005480
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at why some people feel a sharp increase in pain when a numbing injection (nerve block) wears off after surgery. Researchers gave 40 healthy adults a nerve block in one arm and measured pain sensitivity as the block faded. The goal was to understand if the block itself causes temporary extra sensitivity, which could help improve pain management after surgery.
