Abstract
A 77-year-old man underwent transurethral surgery in the lithotomy position under spinal anesthesia. Although bed rest ended the day after surgery, on postoperative day 2 (2POD) he experienced pain in the left leg while walking, which later spread to both legs. Anesthesia had originally proven difficult, and examination by an orthopedic surgeon on 4POD showed no abnormal neurological findings or image findings; on 5POD, he was referred to a pain clinic. The symptom of pain was pain on motion, and trigger points were noted in both legs. He had a history of osteoarthritis of the hip, and his daily living activities had declined. He showed no complications associated with the anesthesia, surgery, or body position on examination at our department; therefore, myofascial pain syndrome was suspected. After starting drug therapy and physical therapy as diagnostic therapy, his symptoms improved, and he was discharged on 10POD.
