You have arrived at the front door of Pilonidal.org, the online home of the Pilonidal Support Alliance. This web site is here to help patients, those who care for them, doctors, and other medical professionals learn about Pilonidal Disease and Pilonidal Cysts (Abscesses.) A Pilonidal (Abscess, Cyst, Sinus, Dimple) is an abscess in the natal cleft (more commonly referred as your butt crack) that tends to become infected and cause intense pain and drainage. This organization’s mission is a simple one: provide a support community where patients can educate themselves about Pilonidal Disease and become fully active partners with their doctors in determining treatment. This site is a gift to those suffering from this lousy disease and it’s thought to be a useful tool to a responsible use. The Pilonidal Support Alliance is a tax-exempt non-profit corporation under IRS regulation, and you can make any donations, which are fully tax deductible. Through this site you will find much information about this disease, as well as institutional information, treatments, community, and many other sections you can access by the links on the left hand side of your screen.
