A study of 2000 cases of back pain referred to hospital found that 2.7% were diagnosed as coccydynia. This type of pain occurs five times more frequently in women than in men. It can occur at any age, the mean age of onset being around 40. There are no ethnicity or race associations with coccydnia.

Activities that put pressure on the affected area are bicycling, horseback riding, and other activities such as increased sitting that put direct stress on the coccyx. The medical condition is often characterized by pain that worsens with constipation and may be relieved with bowel movement. Rarely, even sexual intercourse can aggravate symptoms.
