A Pilonidal Cyst is a blanket term for any type of skin infection near the coccyx. These are normally quite painful, occur somewhat more often in men than in women, and normally happen in early adulthood. Although usually found near the coccyx, this painful condition can be found in several places, including the navel or the armpit.
Development of the condition in a place other than the coccyx is exceedingly rare, however. It usually happens in young people, up to their thirties in age. Conditions in which it commonly occurs include obesity, body hair around the area in question, and a sedentary lifestyle. While a traumatic event is not believed to cause a pilonidal cyst, such an event has been known to inflame existing cysts. (more…)
