Figure 1 Findings on testing for cutaneous allodynia in a woman who developed chronic pelvic pain after uterine artery embolization for postpartum hemorrhage. The lines indicate the initial and subsequently more superior limits of abdominal wall sensitivity. The circles indicate areas of extreme tenderness on testing of pressure thresholds for pain, and indicate the sites of emergence of the anterior cutaneous nerves of the abdominal wall. Botulinum toxin was injected at the four lowest sites (two on each side) Journal of Obstetrics and Gynaecology Canada 2015 37, 628-632DOI: (10.1016/S1701-2163(15)30201-2) Copyright © 2015 Society of Obstetricians and Gynaecologists of Canada Terms and Conditions
