A sciatic hernia is a rare type of hernia that develops in the pelvic area through the sciatic foramen. Unlike other abdominal wall hernias, a swelling or bulge is difficult to detect because of its position under the larger gluteus muscle that covers the back of the pelvis. Sciatic hernia symptoms will depend upon the organs inside of the hernia sac - small intestine, uterus, bladder, ovary and fallopian tube, or colon. Women have a greater risk of sciatic hernia because of the width of their pelvis. Sciatic hernias can develop in children or adults.
