Tailbone pain, called coccydynia, most often results from a direct injury like a fall or from prolonged pressure on the base of your spine. It affects women roughly 2.5 times more often than men, largely because of differences in pelvic anatomy and the added risk from childbirth. The good news is that most cases improve with simple changes at home, though recovery can take weeks to months depending on the cause.
What Your Tailbone Actually Does
Your tailbone (coccyx) is a small, triangular set of fused vertebrae at the very bottom of your spine. Despite its small size, it’s an anchor point for a surprising number of muscles and ligaments. The pelvic floor muscles that support your bladder, bowel, and reproductive organs all attach here, including the levator ani and the pubococcygeus. Your gluteus maximus, the largest muscle in your body, also connects along the sides of the coccyx. Several major ligaments run through the area, and an extensive network of nerves sits just beneath the surface.
Because so many structures converge at the tailbone, pain in this area can come from the bone itself, from the muscles pulling on it, from irritated ligaments, or from the nerves running through it. That’s why tailbone pain can feel different from person to person, and why it sometimes shows up without an obvious injury.
The Most Common Causes
Trauma is the leading cause. About half of all tailbone pain cases trace back to a direct fall onto the coccyx, like slipping on ice or missing a step. The impact can bruise, dislocate, or fracture the bone. Around 26% of patients in clinical studies report a fall as the triggering event, while about 10% develop pain after childbirth. During vaginal delivery, the baby’s head can push the coccyx backward, and the pelvic floor muscles that attach to it can tear or stretch, a particularly common injury to the pubococcygeal segment of the levator ani.
Prolonged sitting is another frequent culprit, especially on hard or poorly padded surfaces. When you sit, your full upper body weight concentrates on a small area of your pelvis. If you sit for hours daily, particularly leaning back, the sustained pressure can inflame the tissues around the tailbone. People with a higher body mass index face additional risk because of the greater load on the coccyx during sitting.
Some people develop tailbone pain without any clear injury. Variations in the shape of the coccyx itself, differences in the small disc-like spaces between its segments, or unusual mobility of the tailbone joints can all play a role. Low mood and depression have also been linked to persistent coccydynia, likely through the way chronic stress increases muscle tension in the pelvic floor.
What Tailbone Pain Feels Like
The hallmark symptom is a deep, aching pain right at the base of your spine that gets worse when you sit down, lean back, or stand up from a seated position. You might also notice it during bowel movements or sex, since both involve the pelvic floor muscles anchored to the coccyx. Some people feel a sharp stab when shifting positions, while others describe a constant dull pressure. Pressing directly on the tailbone typically reproduces the pain, which is also one of the main ways a doctor confirms the diagnosis.
How It’s Diagnosed
A physical exam is usually enough to identify coccydynia. Your doctor will press on the coccyx to check for focal tenderness, and may assess mobility of the tailbone through an external or rectal exam. Standard X-rays can reveal fractures, dislocations, or unusual bone shapes. In some cases, X-rays taken in both sitting and standing positions help identify abnormal movement of the coccyx segments. If the cause remains unclear, an MRI can check for soft tissue problems, infections, or, rarely, tumors in the area.
Relieving Pain at Home
The first and most effective step is reducing pressure on the tailbone when you sit. A U-shaped or wedge-shaped coccyx cushion is the best option. These cushions have a cutout at the back that lets your tailbone hover in open space rather than pressing against the chair. Patients with tailbone pain are nearly five times more likely to prefer this design over a donut-shaped ring cushion. Donut pillows, while popular, can actually make things worse: the central hole allows tissue to sag downward, increasing pressure rather than relieving it.
Beyond cushioning, try to avoid sitting for long uninterrupted stretches. If your work keeps you at a desk, stand or walk for a few minutes every 30 to 45 minutes. When you do sit, lean slightly forward to shift weight onto your thighs and away from the tailbone. Ice applied to the area for 15 to 20 minutes several times a day can help during the first week or two after an injury. After that initial period, some people find alternating between ice and heat more helpful.
Over-the-counter anti-inflammatory pain relievers can take the edge off while you heal. Stool softeners may also be worthwhile if bowel movements are aggravating your pain, since straining puts direct pressure on the coccyx.
Physical Therapy for Persistent Pain
When home measures aren’t enough after several weeks, physical therapy targeting the pelvic floor can make a significant difference. Therapists use a combination of approaches: stretching the piriformis and iliopsoas muscles (deep hip and lower back muscles that pull on the pelvic structures), hands-on mobilization of the coccyx itself, and relaxation techniques for the pelvic floor muscles. Some of these techniques involve internal (rectal) manipulation to release tight levator ani muscles and realign the tailbone, typically over just a few sessions.
External techniques also work well. Sacrococcygeal manipulation, where the therapist works on the joint between the sacrum and coccyx from outside the body, has shown meaningful pain reduction. Therapeutic taping applied from the tailbone outward can provide support between sessions. Exercises like “reverse Kegels,” which train you to relax rather than tighten the pelvic floor, and clamshell exercises for hip stability are commonly prescribed as homework. Postural education and adjustments to how you sit, stand, and even use the toilet round out most treatment plans.
Internal techniques have proven especially effective for people whose coccyx is stiff or slightly misaligned, particularly when the pain has been present for less than a year.
Injections and Nerve Blocks
For pain that persists despite physical therapy, targeted injections can help. Two common options are a ganglion impar block (which numbs a nerve cluster near the tailbone) and a caudal epidural steroid injection (delivered at the base of the spinal canal). Both approaches can reduce pain dramatically in the short term. In one comparative study, all patients in both groups experienced an 80% pain reduction within an hour of injection, and improvements remained significant at three months.
The catch is that the long-term durability of these injections is uncertain. Some people get lasting relief from a single injection, while others need repeat treatments. Injections are generally viewed as a bridge, buying time for other therapies to work or helping confirm that the coccyx is truly the pain source before considering surgery.
When Surgery Becomes an Option
Surgical removal of the coccyx (coccygectomy) is reserved for people who have tried conservative treatment for months without adequate relief. It’s a last resort, not a first-line option. Success rates in published studies range from 60% to 100%, with the best outcomes seen in patients whose pain started after a specific trauma or childbirth (about 75% success) compared to those with no identifiable cause (about 58%).
The main risk is wound infection, since the incision site is close to the rectum. Older studies report infection rates as high as 22%, though newer surgical techniques have brought that down to around 9%. Most infections resolve with wound care and antibiotics without affecting long-term results. Recovery from coccygectomy takes time: you’ll need to limit sitting for several weeks afterward, and full healing may take a few months.
Signs That Something More Serious Is Going On
The vast majority of tailbone pain is mechanical and benign. But certain symptoms warrant prompt medical attention. Pain that radiates down your legs, numbness or tingling in your lower body, or difficulty controlling your bladder or bowels could indicate nerve compression or, very rarely, a tumor called a chordoma that develops near the base of the spine. Unexplained weight loss, pain that worsens at night regardless of position, or tailbone pain that started without any injury and steadily gets worse over weeks are also reasons to get evaluated sooner rather than later.
