When do sciatic symptoms indicate a medical emergency?

Cauda equina syndrome, which can be caused by the dysfunction of bowel and bladder functions, continuous weakness of legs, and saddle anesthesia, is quite serious and calls for immediate medical attention. Saddle anesthesia is the numbness or paralysis in the butt. This is a warning sign of something serious. Saddle anesthesia, along with the disrupted bowel and bladder functioning, is a medical emergency.
