Coccyx Fracture vs Bruise: How to Tell the Difference (2026)
Expert guide on how to tell if your tailbone is fractured or bruised. Compare symptoms, diagnostic methods, treatment options, and recovery timelines for both coccyx injuries.
You cannot definitively distinguish a coccyx fracture from a bruise based on symptoms alone — an X-ray is the only reliable way to confirm a fracture. However, certain patterns of symptoms make one more likely than the other, and understanding the difference helps you make better treatment decisions.

Coccyx Anatomy: Why Injuries Are Common
The coccyx (tailbone) is a triangular bone at the base of the spine, made up of 3–5 fused or semi-fused vertebrae. It sits at the very bottom of your spinal column and bears significant pressure whenever you sit, especially on hard surfaces.
Because the coccyx has limited natural protection — it is covered only by skin, fat, and the gluteus maximus muscle — it is highly vulnerable to direct trauma from falls, childbirth, and sustained pressure.
Symptoms: Fracture vs Bruise
Bruised Coccyx Symptoms
A bruised coccyx involves soft tissue injury and periosteal (bone surface) inflammation without a break in the bone itself:
- Dull to moderate aching pain at the base of the spine
- Pain worsens with sitting, especially on hard surfaces
- Pain on rising from sitting (the "stand-up wince")
- Tenderness to touch over the tailbone
- Mild swelling or bruising visible externally (may be subtle)
- Pain that gradually improves within 2–4 weeks with conservative treatment
Fractured Coccyx Symptoms
A coccyx fracture involves an actual break in the bone:
- More intense, often sharp pain at the base of the spine
- Significant pain on transitioning from sitting to standing
- Pain that may worsen over the first few days rather than improving
- More pronounced tenderness to touch
- Possible palpable deformity (the coccyx may feel angled or displaced)
- Pain that persists beyond 4 weeks without significant improvement
- In some cases, pain radiating into the buttocks or upper thighs
The Key Differences at a Glance
| Feature | Bruised Coccyx | Fractured Coccyx |
|---|---|---|
| Pain severity | Moderate | Moderate to severe |
| Pain trajectory | Improves within 2–4 weeks | May worsen initially; takes 8–12 weeks to improve |
| X-ray findings | Normal or periosteal reaction | Visible break or displacement |
| Sitting pain | Yes | Yes (usually more severe) |
| Deformity on palpation | No | Possible |
| Bowel/bladder changes | No | Rarely, if significant displacement |
| Treatment difference | Conservative only | Conservative + possible injection |
How Diagnosis Works
Physical Examination
A doctor or physiotherapist will:
- Palpate (feel) the coccyx externally to identify the exact point of tenderness
- Assess range of movement of the sacrococcygeal joint
- Potentially perform an internal examination to assess coccyx mobility and alignment
X-Ray
An X-ray is the standard diagnostic test for a suspected coccyx fracture. Because the coccyx naturally varies in shape between individuals, X-rays are taken in both sitting and standing positions to assess for abnormal movement.
Limitations of X-ray: Subtle fractures can be missed on plain X-ray, particularly in the acute phase. MRI provides more detailed information about soft tissue injury and subtle bone injuries.
MRI
Recommended for:
- Significant trauma with ongoing pain
- Suspected spinal cord or nerve involvement
- Ruling out other causes of tailbone pain (such as tumours or infection)
- Cases where X-ray is inconclusive
Do I Need an X-ray?
An X-ray is recommended if:
- You experienced significant trauma (hard fall, car accident)
- Pain is severe and not improving after 1–2 weeks
- You have signs suggesting a fracture: visible deformity, inability to sit, pain that worsens over time
- Pain is accompanied by neurological symptoms (numbness, tingling, weakness)
Treatment
Treatment for both a bruised and fractured coccyx is initially the same — conservative management. There is no cast or brace that can be applied to the coccyx.
Conservative Treatment (Both Fracture and Bruise)
1. Coccyx cushion A cushion with a U-shaped rear cutout is essential for anyone with a coccyx injury. It eliminates direct pressure on the tailbone during sitting.
2. Pain management
- NSAIDs (ibuprofen, naproxen) reduce inflammation and pain
- Paracetamol/acetaminophen for pain without significant inflammation
- Ice for the first 48–72 hours; heat after 72 hours
3. Activity modification
- Avoid prolonged sitting on hard surfaces
- Stand frequently (every 30–45 minutes when sitting)
- Sleep on your side or front to avoid direct pressure on the coccyx
4. Physiotherapy Especially helpful for restoring mobility and addressing muscular tension around the coccyx once the acute phase has passed (typically after 3–4 weeks).
Additional Treatment for Fractures
If a fracture is confirmed and pain is severe or not responding to conservative management:
Corticosteroid injection An injection into the sacrococcygeal joint or surrounding tissue reduces inflammation and provides significant pain relief for many patients. Effects typically last 4–12 weeks.
Manual manipulation A physiotherapist or chiropractor can perform internal or external coccyx manipulation to realign a displaced fragment. Most effective in the first few weeks after injury.
Recovery Timelines
Bruised Coccyx
- Typical recovery: 4–6 weeks with conservative treatment
- Back to desk work: Usually within 1–2 weeks (with a coccyx cushion)
- Back to exercise: 3–4 weeks for most low-impact activity
- Full recovery: 6–8 weeks in most cases
Fractured Coccyx
- Typical recovery: 8–12 weeks
- Back to desk work: 3–6 weeks (with a coccyx cushion and frequent breaks)
- Back to exercise: 8–12 weeks for low-impact activity
- Full recovery: 12–16 weeks in most cases; some fractures take longer
Note: In both cases, some people develop chronic coccydynia — ongoing pain lasting more than 3 months. Early physiotherapy intervention is associated with shorter recovery times.
Red Flags: When to Go to A&E
Seek emergency care immediately if you experience:
- Bowel or bladder dysfunction (inability to control or significant changes in function)
- Numbness or weakness in both legs
- Numbness in the saddle area (inner thighs, groin, buttocks) — this may indicate cauda equina syndrome, a medical emergency
- Fever alongside tailbone pain — possible infection
- Pain following high-energy trauma (car accident, fall from height) — possible spinal injury
- Progressive weakness in the legs after an injury
These symptoms require urgent imaging and specialist assessment, not just rest and a coccyx cushion.
Frequently Asked Questions
How can I tell if my tailbone is fractured or just bruised? You cannot definitively tell based on symptoms alone — only an X-ray confirms a fracture. However, fractures tend to cause more intense pain that may worsen over the first few days, visible swelling or deformity, and pain that persists beyond 4 weeks without improvement. A bruised coccyx typically produces moderate pain that gradually improves within 2–4 weeks.
How long does a bruised tailbone take to heal? A bruised coccyx typically takes 4–6 weeks with conservative treatment. Most people notice significant improvement within the first 2–3 weeks. Use a coccyx cushion, avoid prolonged sitting, ice for the first 48–72 hours, then heat, and take over-the-counter pain relievers as needed.
How long does a fractured tailbone take to heal? A fractured coccyx typically takes 8–12 weeks, though some fractures take longer depending on severity and individual health factors.
Can a fractured tailbone heal on its own? Yes, most coccyx fractures heal on their own with conservative treatment. Surgery (coccygectomy) is only considered in rare cases where the fracture fails to heal after several months of conservative care.
Should I go to A&E for tailbone pain? Seek emergency care if you experience bowel or bladder dysfunction, numbness in the saddle area, progressive leg weakness, fever, or if the injury resulted from high-energy trauma. For moderate tailbone pain after a fall, booking an urgent GP or physiotherapy appointment within a few days is usually appropriate.
