This report describes a case of ultrasound-guided fascia hydrorelease (US-FHR) used to treat persistent pain on walking of more than 20 years' duration. The patient, a man in his 80s, developed pain on walking in the right lateral femoral area after surgery for cervical spine disease more than 20 years earlier. Nerve blocks and other treatments were ineffective. He visited a pain clinic at Asahikawa Medical University Hospital and started taking pregabalin 50 mg/day, which decreased the pain, but caused side effects such as drowsiness. When the pain on walking worsened, we found muscle stiffness and pressure pain in the same area, and ultrasound showed a fascial overlap of the right vastus lateralis muscle. US-FHR with 20 ml of 0.025％ lidocaine around the overlap resulted in complete disappearance of the pain for a week. US-FHR was repeated and long-term pain improved. Finally, satisfactory pain control was achieved with only a low dose of mirogabalin.
