Few things are as disruptive to daily life as pain that strikes just by sitting down. Whether it surfaces during a long commute, a full workday, or simply settling into a chair for dinner, tailbone pain has a way of making even routine moments feel frustrating and exhausting.
Women are disproportionately affected, as are active individuals, and those who spend long hours seated are also commonly impacted.
Whatever the underlying cause, tailbone pain is rarely something to push through without answers.
What Is the Tailbone Anatomy — and Why Does It Hurt?
The coccyx, commonly called the tailbone, is the small, triangular bone at the base of your spine. Though modest in size, it serves as an important attachment point for several muscles, tendons, and ligaments involved in posture and movement.
A large portion of your body weight is distributed across the coccyx and the surrounding structures when you sit, which is why this area is particularly vulnerable to both acute injury and chronic irritation.
Coccydynia is the clinical term for pain localized to the coccyx region. It can result from direct trauma, prolonged pressure, or dysfunction like hyper or hypomobility of the coccygeal joints. Because the coccyx sits adjacent to the SI joint and the lower sacral nerve roots, a precise diagnosis is essential—what feels like tailbone pain may not always originate there.
Common Causes of Tailbone Pain When Sitting
Tailbone pain rarely has a single, universal cause. A thorough evaluation is needed to identify the specific structural or functional driver. The most frequently identified causes include:
- Acute trauma: A fall directly onto the coccyx is one of the most common triggers, leading to bruising, fracture, or dislocation of the coccygeal segments.
- Repetitive strain: Cycling, rowing, and other activities that involve sustained seated pressure can cause cumulative irritation of the coccyx over time.
- Pregnancy and childbirth: Hormonal changes that loosen pelvic ligaments, combined with the mechanical forces of delivery, frequently cause or aggravate coccyx pain.
- Coccygeal hypermobility or hypomobility: Excessive or restricted movement at the coccygeal joint can produce pain even in the absence of obvious injury.
- Degenerative changes: Degenerative conditions, such as arthritis, affecting the coccygeal or sacrococcygeal joints, can contribute to chronic, position-dependent pain.
How Is Tailbone Pain Diagnosed?
Because multiple structures can produce overlapping symptoms in this region, getting an accurate diagnosis involves more than identifying a single point of tenderness. This is why our board-certified, fellowship-trained physiatrists and pain management physicians begin with a detailed history and a comprehensive physical examination, assessing posture, movement patterns, and pain behavior with both static and dynamic loading. Imaging, including X-rays and MRI, can reveal fractures and dislocations, arthritis, or other structural contributors.
Non-Surgical Tailbone Pain Treatment Options
Most cases of coccydynia improve significantly with the right non-surgical approach.
Effective non-surgical options may include:
- Activity modification and ergonomic support: Coccyx-relief cushions, posture adjustments, and targeted activity guidance to reduce direct loading on the coccyx.
- Physical therapy: An individualized, specialized pelvic floor therapy program to address coccygeal alignment, pelvic floor dysfunction, muscle imbalances, and movement patterns that contribute to ongoing pain.
- Fluoroscopically guided coccyx injections: Corticosteroid injections delivered with precision imaging guidance to reduce inflammation and localized pain at the coccygeal joint. These injections are combined with ganglion impar blocks for the most effective relief.
- Platelet-Rich Plasma (PRP) therapy: For patients with chronic coccygeal pain, PRP may support connective tissue healing and longer-term stabilization.
