Abstract

|

|
Piriformis syndrome consists of pain, tingling sensation, and paresthesia in areas innervated by sciatic nerve and is one of the main causes of low back pain. A 43-year-old male made a visit for continuous left buttock pain and tingling sensation in lower limbs for three years. Medication, epidural block and sacroiliac joint block were performed, but without effect. Sciatic nerve block with local anesthetics and steroid, however, showed some improvement for a short period of time. The patient’s symptoms, physical examination, and the fact that sciatic nerve block showed improvement for a while led to the suspicion of piriformis syndrome. Thus, pulsed radiofrequency was performed on sciatic nerve twice. Visual analog scale (VAS) was 8-9 on first visit, which decreased to 1 after treatment and lasted for more than 18 months.
