Show Notes
Author: Erik Verzemnieks, MD
Educational Pearls:
- Single study in Japan demonstrated possible effectiveness of renal colic trigger point
- Patients had injection at the area of maximal tenderness on palpation of the flank
- Compared to a muscle relaxer, injection of local anesthetic at the trigger point had faster time to pain relief and fewer rescue therapies
