Why Does My Tailbone Hurt When I Sit?

Tailbone pain when sitting typically results from pressure on the coccyx bone or surrounding tissues. This condition, called coccydynia, affects approximately 1 in 100,000 people annually. Common causes include trauma from falls, prolonged sitting on hard surfaces, childbirth, or degenerative joint changes. Poor posture while sitting can compress the tailbone against your chair, creating inflammation in nearby ligaments and muscles. Pregnancy hormones can also soften pelvic ligaments, making the tailbone more sensitive. The pain often worsens with direct pressure and improves when standing or leaning forward while seated.
