Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

Patients with chronic abdominal pain- with a component of abdominal wall pain- are often treated with trigger point injections. This study will help to determine if a block within the transversus abdominis plane (TAP) will provide superior analgesic benefit to a trigger point injection as therapy for these patients.
