Abstract
Coccygeal plexus neuralgia or coccygodynia is generally hysterical and is practically limited to women. The pain is severe in the tip of the coccyx, which is generally tender. It occurs on sitting, standing, or walking; it is generally spontaneous. The pain may come on after trauma or childbirth, possibly following slight inflammation. The affection is most stubborn. Psychotherapy is the best form of treatment.
