Coccydynia is often caused by an injury, but it may occur seemingly spontaneously. There are many causes of tailbone pain that can mimic coccydynia, including sciatica, infection (including shingles of the buttocks), pilonidal cysts, sacroiliitis, and fractured bone (broken tailbone or tailbone fracture).
Characteristics: Curium is a hard, dense radioactive silvery-white metal. It tarnishes slowly in dry air at room temperature. Most compounds of trivalent curium are slightly yellow in color. Curium is highly radioactive and it glows red in the dark.

This element of the actinide series was named after Marie and Pierre Curie â both were known for their research on radioactivity. Curium was first intentionally produced and identified in July 1944 by the group of Glenn T. Seaborg at the University of California, Berkeley.
