Usefulness of a Myofascial Trigger Point Injection for Groin Pain in Patients With Chronic Prostatitis/Chronic Pelvic Pain Syndrome: A Pilot Study

In patients with CP/CPPS, US-guided trigger point injections of the iliopsoas, hip adductor, and abdominal muscles are safe and effective for both diagnosis and treatment when the cause of groin pain is suspected to originate from muscles. In particular, the iliopsoas muscle was affected in all patients in this study.
