Pilonidal disease leaves teenagers and young adults prone to painful tailbone infections

Pilonidal disease develops when hair becomes lodged beneath the skin at the top of the buttocks, close to the tailbone. The condition is seen most often in teenagers and young adults, particularly those between about 15 and 30 years old.

Several factors raise a person's likelihood of developing the disorder. Patients with dense body hair, especially stiff or brittle strands, are more vulnerable, as are people who are obese or who must sit for extended periods. Hair in the tailbone area—the lower portion of the spine—is typically involved. Long sitting and coarse hair can push strands into the skin rather than allowing normal outward growth.

Globally, pilonidal disease affects approximately 70,000 people per year, with most cases occurring in the 15-to-30 age group. Medical sources indicate that no specific prevalence data exists for Jamaica.

Over time, embedded hair can penetrate deeper layers of skin and trigger infection. Symptoms may include tenderness, pain, redness, and swelling consistent with an abscess in the lower tailbone region. Some patients notice drainage from the back. A course of antibiotics may settle one flare-up, but the pattern often repeats.

During a physical examination, clinicians frequently identify a small sinus in the tailbone area—findings that are regarded as characteristic of the condition.

Treatment options include surgical, non-surgical, and laser approaches. Surgery is generally considered once a patient becomes symptomatic. Surgeons note that pilonidal sinus removal carries a relatively high recurrence rate compared with other procedures commonly performed on children and teenagers, making durable resolution an important treatment aim.
