How Do I Know If I Fractured My Tailbone? The Advice That Does Not Hold Up
You cannot reliably tell at home whether a hard fall has fractured the tailbone or only bruised it. WebMD, medically reviewed by Carol DerSarkissian, MD, on 14 May 2026, states there is often no way to tell without an X-ray, that pain is usually worse with a fracture but not always, and that most tailbone injuries are bruises. The NHS page on tailbone (coccyx) pain, last reviewed 20 November 2025, does not ask anyone to diagnose a crack. It tells people to ease sitting pressure and to see a GP if pain has not improved after a few weeks of home treatment. MedlinePlus, reviewed 7 October 2024 by Jesse Borke, MD, FAAEM, FACEP, puts bruise healing at about 4 weeks and fracture healing at 8 to 12 weeks, and says surgery is not discussed until 6 months or more after the injury. The useful split is whether nerve, bowel, bladder or fever signs are present, and whether the pain trend is settling or climbing.
A doughnut ring is not the cushion the specialist papers prefer. A standing lumbar film often never includes the bone people think they have imaged.
Emergency jewellery work has the same problem. When a finger swells around a stuck ring, the metal does not disclose whether the bone underneath is intact. Colour, time since the injury, and whether sensation is still arriving decide whether the ring is worked off or cut. A coccyx after a fall answers to the same three clocks.
Can you tell a fractured tailbone from a bruise without a scan?
healthdirect, last reviewed March 2026, says patients usually will not need X-rays, CT or MRI, and that those scans are used to rule out infection, tumours or fractures. WebMD still treats the X-ray as how a crack is known. Those two positions sit without a referee.
Patrick M. Foye, M.D., Professor of Physical Medicine and Rehabilitation at Rutgers New Jersey Medical School and Director of the Coccyx Pain Center, adds a third problem. In a 19 January 2016 Rutgers University report by Eve Jacobs, Foye said most lower-spine X-rays are taken standing and rarely reveal coccyx problems. "In order to evaluate this condition, an X-ray needs to be taken while the patient is sitting," he said. He also said a standard lumbar MRI, often ordered for tailbone pain, does not even include the coccyx. WebMD and Foye both describe the coccyx as three to five bony segments.
Leicester's Emergency Department leaflet Managing tailbone (coccyx) injuries or pain (leaflet 1736, April 2026) adds a marble-like pressure on sitting. MedlinePlus and the NHS list sitting pain, bruising and pain on a poo. None of those lists is labelled "fracture only."
| | Suspected fracture | Contusion (bruise) | Coccydynia, no proven crack | | --- | --- | --- | --- | | Known at home | Not reliably (WebMD) | Not reliably | Pain at the spine base; a fall is not required | | Healing window | 8 to 12 weeks (MedlinePlus; Leicester 1736) | About 4 weeks (same sources) | NHS: a few weeks, sometimes longer | | What A&E does | History, exam, aftercare. healthdirect: scans often unused | Same package | Same package after a fall | | GP clock | Leicester: not starting to improve in 6 to 8 weeks | NHS: not improved after a few weeks at home | Same NHS clock if daily life is affected |
Walking can continue with a crack. A standing film can look normal. Sitting can be wretched with an intact bone.
Which symptoms after a fall onto the tailbone need urgent assessment?
Homerton Healthcare NHS Foundation Trust tells people to contact a GP or NHS 111 immediately for back pain with numbness or tingling around the genitals or buttocks, difficulty peeing, loss of bladder or bowel control, chest pain, a high temperature of 38C (100.4F) or above, unexplained weight loss, a swelling or deformity in the back, pain that does not improve after rest or is worse at night, or pain after a serious accident such as a car crash.
NHS England's Getting It Right First Time (GIRFT) National Suspected Cauda Equina Syndrome Pathway, February 2023, signposted from NICE NG127 (updated 20 June 2025), puts a clock on the numbness. The Humber and North Yorkshire pathway, quoting GIRFT, treats new or deteriorating saddle sensation or urinary-flow change within 2 weeks as an emergency MRI referral. Symptoms already lasting 14 days or more, and now static, go to urgent musculoskeletal services. MedlinePlus does not use that 14-day split. It tells readers to contact a provider for sudden numbness, tingling or weakness in the legs, a sudden rise in pain or swelling, or bowel or bladder control problems.
Sudden saddle numbness with a bladder that will not start is not a wait-and-see bruise. Numbness unchanged for three weeks is still a medical problem.
Fever splits on speed, not on the reading. The NHS high-temperature page, last reviewed 24 May 2023, says a high temperature is usually considered to be 38C or above. Homerton treats 38C with back pain as immediate. The NHS coccyx page files high temperature plus tailbone pain plus pain in the tummy or lower back under non-urgent GP advice. Leicester's leaflet tells people to see a GP for fevers, abdominal or higher-back pain, and bleeding from the bottom. Nobody on that list treats 38C plus tailbone pain as a doughnut-pillow evening.
healthdirect wants a doctor for pain getting worse over a few weeks, distress, limited movement, or a significant injury. If sitting and standing are already difficult after a hard fall, that limited-movement item should pull the visit forward even when saddle numbness is absent.
What can a clinician learn from the mechanism, the exam, and the pain trend?
MedlinePlus and Leicester both name a backward fall onto a hard surface, such as ice or a slippery floor, as the typical injury. WebMD adds contact-sport blows, childbirth, cycling, rowing and long sitting. The NHS says the cause is sometimes unknown. A high-energy crash sits in Homerton's "serious accident" bucket.
WebMD describes a spinal exam for tenderness and, in some cases, a rectal exam; direct pressure reproducing the pain is the localising finding. Foye's sitting radiograph is the imaging version of that sitting stress. healthdirect's usual path is history plus examination without a scan.
NICE guideline NG59, last reviewed 29 July 2026, treats a rating of 5 or more on a visual analogue scale, or equivalent, as moderate or severe localised back pain when later options such as radiofrequency denervation are considered. That number is not a home fracture test. healthdirect wants a doctor if pain is getting worse over a few weeks. Leicester wants a GP if pain does not start to improve within 6 to 8 weeks. The NHS coccyx page uses "a few weeks" of home treatment. Those intervals do not match. Pain still climbing at day ten is on healthdirect's clock. Pain slowly easing at week five is still inside Leicester's window.
WebMD reports that women are five times more likely to have coccyx injuries than men because the female pelvis is broader and the coccyx is more exposed.
Which sitting, movement, and self-care choices actually take pressure off?
MedlinePlus and WebMD both recommend a gel doughnut with a hole in the centre. Leicester offers that ring or a wedge-shaped "coccygeal cushion." The NHS names a "specially designed coccyx cushion" without specifying a ring. healthdirect names the wedge.
Foye, Sean O. Sanderson and Jason A. Smith published the numbers that should have retired the ring-first instruction. In the American Journal of Physical Medicine and Rehabilitation, March 2009, 88(3):S56, they reviewed 55 patients who had tried both (40 women, 15 men, average age 49). Nineteen (35 percent) preferred the wedge; four (7 percent) preferred the donut; four (7 percent) liked both; 23 (42 percent) preferred neither. Patients with a preference were almost five times more likely to prefer the wedge. coccyx.org, updated 27 May 2026, states the mechanical reason: ring cushions take pressure off the genitals and may increase pressure on the coccyx. A rear cut-out lets the tailbone hover.
Ice is the other number treated as fixed. The NHS says 20 to 30 minutes, wrapped, and allows a heat pack for longer. MedlinePlus says about 20 minutes every hour while awake for the first 48 hours, then two to three times a day, not on bare skin. Leicester says 10 to 15 minutes every few hours for the first 3 days. WebMD says 15 to 20 minutes, four times a day, for the first few days. None of those clocks is "leave ice on until the skin goes numb."
Sleep splits too. The NHS and Leicester say lie on the side. MedlinePlus says lie on the belly.
- Check red flags the same day: saddle numbness, new bowel or bladder change, leg weakness, fever at 38C, or a high-energy crash.
- Offload sitting with a rear cut-out or wedge, short sits, a forward lean, and weight on alternate buttocks (MedlinePlus; WebMD). Leicester adds that sitting without the cushion must be rebuilt slowly.
- Ice the area on a wrapped pack using one of the schedules above, then heat if cold has not helped.
- Soften stools with fibre, fluid and a stool-softening laxative if needed. MedlinePlus names ibuprofen, naproxen or acetaminophen, with organ and bleeding cautions, and says not to give aspirin to children. Keep moving within pain: Leicester says stay mobile; Homerton says long rest makes back pain worse; MedlinePlus says rest from activity that hurts.
- Review with a GP if pain has not started to improve at the leaflet interval (NHS: a few weeks; Leicester: 6 to 8 weeks).
If pain lasts past the early weeks, what recovery and follow-up look like?
MedlinePlus, Leicester and WebMD give about 4 weeks for a bruise and 8 to 12 weeks for a fracture. A broken tailbone can heal on its own in that stretch. Leicester says non-surgical treatment works in about 9 out of 10 cases, or 90 percent of the time. healthdirect uses the same fraction for coccyx pain resolving without medical treatment.
The NHS says the pain may improve after a few weeks and can last longer. healthdirect says weeks to months, sometimes becoming chronic. MedlinePlus says a steroid injection may be tried if symptoms do not improve, and that surgery is not discussed until 6 months or more after the injury. WebMD uses the same six-month floor. The NHS lists physiotherapy and corticosteroid plus local anaesthetic injections as the next treatments if simple measures have failed.
Foye, in the same Rutgers interview, rejected the older fork in the road. "Either patients were told it was all in their minds and were dismissed; or if the pain was bad enough, tailbone amputation was recommended," he said. Surgical recovery, he said, takes six months to a year, with a high infection rate because of the location next to the anus.
MedlinePlus says a provider may not need to follow up if healing is as expected. Leicester's 6-to-8-week mark is the GP visit that catches people still unable to sit through a meal. From that point the question is whether physiotherapy, injection or a sitting radiograph is next, and whether a delayed red flag was missed.
The advice that does not hold up is the sentence from the night of the fall: that the first sit would reveal a fracture. The leaflets promised a pain course, a fever number, a numbness clock, and a healing window twice as long for a crack as for a bruise.
Frequently asked questions
How can you tell if your tailbone is broken or just bruised?
WebMD, medically reviewed on 14 May 2026, says there is often no way to tell without an X-ray. Pain is usually worse with a fracture, but not always, and most tailbone injuries are bruises. The NHS does not ask for a home crack-versus-bruise verdict. It follows whether pain eases after a few weeks of aftercare and whether red-flag signs appear.
Does a broken tailbone heal on its own?
Leicester's April 2026 emergency leaflet (number 1736) says non-surgical treatment works in about 9 out of 10 cases. MedlinePlus, reviewed 7 October 2024, puts fracture healing at 8 to 12 weeks and bruise healing at about 4 weeks. Surgery to remove part of the tailbone is not discussed until 6 months or more after the injury.
Can a broken tailbone go unnoticed?
Yes. WebMD notes that X-rays occasionally may not reveal a fracture or dislocation. Patrick M. Foye, M.D., of Rutgers New Jersey Medical School, reports that standing lumbar films and standard lumbar MRI often miss the coccyx. Walking can continue. Pain when sitting, or a marble-like pressure, may be the only clue until weeks have passed.
What will the ER do for a broken tailbone?
Leicester's emergency leaflet treats the visit as pain control and aftercare, not a plaster. Clinicians take a history, examine the area, and advise offloading, ice, stool softeners and a GP review if pain is not starting to improve within 6 to 8 weeks. healthdirect says X-rays, CT and MRI are usually not needed.
How long does fractured-tailbone recovery take?
MedlinePlus and Leicester both put fracture healing at 8 to 12 weeks and a bruise at about 4 weeks. The NHS says tailbone pain may improve after a few weeks and can last longer. If physiotherapy and injections fail, the NHS may discuss surgery. MedlinePlus waits 6 months or more after the injury before that discussion.
Which symptoms need urgent assessment?
Homerton Healthcare NHS Foundation Trust says contact a GP or NHS 111 immediately for back pain with numbness or tingling around the genitals or buttocks, difficulty peeing, loss of bladder or bowel control, or a high temperature of 38C (100.4F) or above. NHS England's GIRFT pathway treats new or deteriorating saddle numbness within 14 days as an emergency MRI problem.
