Coccygodynia

Common causes: anorectal infection, chronic trauma involving poor sitting posture, acute trauma, and parturition.
The pain originates in spasm of the levator ani and coccygeus (and at times in the mesial fibers of the gluteus maximus) muscles.
X-ray examination is of diagnostic value only in cases of suspected fracture or dislocation. MRI is the investigation of choice.
Relief obtained by injections of alcohol, or of various anesthetic agents, with or without cortisone.
Treatment by properly applied massage of the levator ani and coccygeus muscles, and at times of the mesial fibers of the gluteus maximus muscle gives relief.
