The plaintiff suffered chronic pain in a scar from a previous hernia operation. The defendant administered spinal phenol to destroy the appropriate pain-conducting nerves which she consented to although she had not been informed of the associated risks. Following the second injection, the plaintiff's right leg was left numb and her mobility was affected. She alleged that her consent was invalid because she had not been warned of these risks. Given the conduct of the matter, what is the reasoned judgment in this case?
