Coccydynia is pain located in the tailbone area, which is the small triangular bone at the very bottom of the spine. The discomfort may feel sharp, aching, or pressure-like and is often noticed when sitting, especially on hard surfaces or during movements that place stress on the lower spine. Coccydynia can develop after trauma to the tailbone, repetitive strain, prolonged sitting, or sometimes without a clearly identifiable cause.
The condition affects the region where muscles, ligaments, and nerves attach around the coccyx, making the area sensitive to pressure and movement. Pain may worsen with activities such as sitting, rising from a seated position, or leaning backward. Because the tailbone area plays a role in weight distribution when sitting, irritation in this region can lead to persistent discomfort and localized tenderness.
