A broken tailbone produces a sharp, aching pain right at the base of your spine, centered between your buttocks. The pain is intense enough that sitting on a hard surface can feel unbearable, and even shifting your weight or standing up from a chair can send a jolt through the area. If you’re dealing with this kind of localized, position-dependent pain after a fall or impact, a tailbone fracture is a real possibility.
Where the Pain Shows Up
The tailbone, or coccyx, is a small triangular bone at the very bottom of your spine. When it fractures, the pain is concentrated in a very specific spot. If someone asked you to point with one finger to where it hurts most, you’d point far lower than typical back pain and right along the midline, not off to one side like a hip or buttock issue. That pinpoint tenderness is one of the hallmark signs.
The pain itself can shift character. It may feel sharp when you move, dull and throbbing when you’re still, or aching after a long period of sitting. Many people describe a deep soreness that never fully lets up, punctuated by stabs of sharper pain during certain movements. You’ll likely also notice bruising and swelling around the base of the spine, though the amount varies depending on the severity of the injury.
Activities That Make It Worse
Sitting is the biggest trigger. Hard chairs, car seats, and bleachers put direct pressure on the fractured bone, and the longer you sit, the worse it gets. But it’s not just sitting itself. The transition from sitting to standing is often the most painful moment, producing a sharp flare as the muscles and ligaments around your tailbone shift.
Other everyday activities can be surprisingly painful:
- Bowel movements increase pressure in the pelvic floor and can intensify pain significantly.
- Leaning backward in a chair compresses the coccyx against whatever surface you’re on.
- Sex can be painful due to the proximity of pelvic structures to the tailbone.
- Cycling or rowing involves repetitive forward-and-back motion that strains the tissues around the coccyx.
Even lying on your back can be uncomfortable if your mattress is firm. Most people with a broken tailbone instinctively start sitting shifted to one side or leaning forward to keep weight off the area.
Broken vs. Bruised: Can You Tell the Difference?
Honestly, often you can’t, at least not by feel alone. A badly bruised tailbone and a fractured one produce very similar symptoms: localized pain, swelling, bruising, and pain with sitting. The main clue is intensity. Pain is usually worse with a fracture than a bruise, but not always. Some bruises are agonizing, and some hairline fractures are surprisingly manageable.
The real difference shows up in healing time. A bruised tailbone typically resolves in about 4 weeks. A fracture takes 8 to 12 weeks to heal. So if your pain hasn’t improved after a month, that’s a signal the injury may be more serious than a bruise.
The only reliable way to distinguish the two is imaging. A doctor can order X-rays, though these occasionally miss tailbone fractures, especially when the bone fragments stay aligned. In those cases, an MRI or CT scan can reveal signs like bone marrow swelling that confirm a fracture the X-ray couldn’t detect. During a physical exam, your doctor may also press along the spine to check for tenderness or perform a rectal exam to feel for displacement or fracture from the inside.
What Recovery Looks Like
Most broken tailbones heal without surgery, but the recovery period is slow and uncomfortable. Expect 8 to 12 weeks before the bone fully heals, with gradual improvement over that window. The first two to three weeks tend to be the worst, with pain during almost any seated activity.
A few strategies make a real difference during recovery. A cushion with a U-shaped cutout (sometimes called a coccyx cushion or donut pillow) removes direct pressure from the tailbone when you sit. These are more effective than standard donut pillows because they specifically offload the coccyx rather than just creating a hole in the center. Look for one with firm memory foam so it doesn’t compress flat under your weight.
Beyond cushioning, leaning forward slightly when you sit shifts pressure away from the tailbone and onto your thighs. Ice applied to the area for 15 to 20 minutes at a time helps with swelling and pain in the first few days. Over-the-counter anti-inflammatory pain relievers can take the edge off, and stool softeners help reduce pain during bowel movements by minimizing straining.
Signs the Injury Needs Attention
Most tailbone injuries, even fractures, are manageable at home. But a sudden increase in pain or swelling after the initial injury warrants a call to your doctor, as it could indicate the fracture has shifted or an infection is developing. Numbness or tingling in the area, difficulty controlling your bladder or bowels, or weakness in your legs are more urgent signs that the injury may be affecting nearby nerves, and these need prompt evaluation.
If your pain hasn’t meaningfully improved after 4 to 6 weeks of home care, imaging can help clarify whether you’re dealing with a fracture, a dislocation, or another issue like chronic inflammation that might need a different approach.
