Two commonly used treatments are trigger point injections (TPI) and erector spinae plane (ESP) blocks, but no studies have directly compared their effectiveness for chronic thoracic myofascial pain. The purpose of this study is to compare pain relief, physical function, emotional well-being, patient satisfaction, and safety following treatment with either an ESP block or TPI.
