One way of classifying<unk>  is whether the onset was traumatic versus non-traumatic. In many cases the exact cause is unknown and is referred to as idiopathic<unk> .<unk>  is a fairly common injury which can often result from falls, particularly in leisure activities such as cycling and skateboarding.<unk>  is often reported following a fall or after childbirth. In some cases, persistent pressure from activities like bicycling may cause the onset of coccyx pain.<unk>  due to these causes usually is not permanent, but it may become very persistent and chronic if not controlled.<unk>  may also be caused by sitting improperly thereby straining the coccyx. Rarely,<unk>  is due to the undiagnosed presence of a sacrococcygeal teratoma or other tumor in the vicinity of the coccyx.
