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.
Source: Curium does not exist in nature. It is a synthetic element and it is produced in nuclear reactors by bombarding plutonium with neutrons. Isotopes: Curium has 15 isotopes whose half-lives are known, with mass numbers 238 to 252.Curium has no naturally occurring isotopes.ource: Curium does not exist in nature.
