If sitting down is the worst part of your day, and standing back up is somehow worse still, you are describing tailbone pain almost exactly. It is a small problem anatomically and a large one practically, because it interferes with desks, car journeys, meals, flights and evenings on the sofa.
The medical name is coccydynia, which simply means pain in the coccyx. It turns up after a fall onto the bottom, after childbirth, and in people who spend long hours on hard seats. A good number of people develop it with no obvious trigger at all.
The reassuring headline is that most tailbone pain settles. The frustrating part is that it often settles slowly, and the things that help most are unglamorous: what you sit on, how you sit, and how often you get up.
What the coccyx is, and why such a small bone hurts so much
The coccyx is the small, tapering bone at the very bottom of your spine, made of three to five little segments that are partly fused together. It gets called a vestigial tailbone, which rather undersells how much work it does.
When you sit, your weight is carried on a tripod: the two sitting bones and the coccyx. Lean back and more of that load transfers onto the coccyx itself. The bone is also an anchor point for pelvic floor muscles, several ligaments and part of the large buttock muscle, so it sits inside a busy web of soft tissue that pulls on it whenever you move.
That combination explains why something so small can dominate your day: a bone with a rich nerve supply, sitting directly under your body weight, tethered to muscles that never stop working. Once the joint at the top of the coccyx is irritated, ordinary sitting becomes a repeated provocation rather than a rest.
What coccydynia feels like
Coccyx pain is typically a deep ache or a sharp, pinpointed pain right at the base of the spine, clearly worse when sitting and worse again in the moment you stand up.
The pattern is usually distinctive:
- Pain localised to a small area at the very bottom of the spine, often tender if you press on it.
- Worse sitting, particularly on hard chairs, and particularly when you lean back.
- Worse rising from sitting, that first movement out of the chair is often the sharpest second of the day.
- Sometimes uncomfortable with bowel movements or during sex, because of the pelvic floor and ligament attachments.
- Often easier standing, walking or lying down, which is why people with coccydynia end up pacing at the back of meeting rooms.
How it differs from ordinary low back pain
Most lower back pain sits higher, in the belt of muscle and joint above the pelvis, and is provoked by bending, lifting and twisting. Coccyx pain sits lower, is far more precisely located, and is dominated by sitting rather than movement. If you are still working out which pattern fits, our guide to what causes lower back pain covers the common sources.
When it is not actually the coccyx
Pain felt in that region does not always come from the coccyx itself. The sacroiliac joints sit just above and to either side, and irritation there can be felt low and deep in a way that is easy to confuse. Sacroiliac pain is usually a little off to one side rather than dead center, and it is often provoked by standing on one leg or rolling over in bed. If that sounds closer to your experience, read about sacroiliac joint pain.
What triggers tailbone pain
Four situations account for most cases: a fall onto the tailbone, childbirth, prolonged sitting on unforgiving surfaces, and no identifiable event whatsoever.
A fall onto the tailbone
Landing hard on your bottom, on ice, on stairs, in the shower, off a bike, is the classic cause. The force goes straight through the coccyx. That can bruise the bone, strain the ligaments around it, or fracture or dislocate one of the segments. In practice the distinction matters less than people expect, because the early management is much the same either way.
Childbirth
During delivery the coccyx has to move backwards to let the baby through. That is normal and usually uneventful, but a long or difficult labour, or a large baby, can leave the joint strained, hypermobile or occasionally injured. Coccyx pain that starts in the weeks after giving birth is common, under-reported, and responds well to pelvic-floor-informed physiotherapy.
Long hours of sitting
Sitting is a genuine cause rather than just an aggravator. Hours on hard chairs, narrow bike saddles, low deep sofas or a car seat on a long commute keep the coccyx loaded and can gradually irritate the joint. This is the same mechanical story behind much of the back pain that builds up at a desk, just concentrated on one small bone.
No clear cause at all
For a meaningful proportion of people, nothing happened. No fall, no delivery, no new chair. Weight change in either direction can alter how you load the area, as can a long illness spent sitting. Sometimes the honest answer is that the trigger was never identified, and that does not make the pain less real or less treatable.
Why tailbone pain often gets brushed off
Coccyx pain gets dismissed because it is invisible, awkwardly located and easy to make jokes about. There is nothing to see, nothing swollen to point at, and the word tailbone sounds faintly comic to everyone except the person who has it.
Patients often say they waited months before mentioning it, or that they were told to sit on a rubber ring and get on with it. Meanwhile they had stopped driving long distances, stopped eating out, and were standing through meetings.
Coccyx pain is not a trivial complaint dressed up with a medical name. It is a real, mechanical problem in a bone that carries your weight every time you sit down.
Self-care that genuinely helps
The most effective self-care is unloading the coccyx while it settles: the right cushion, a small change in sitting posture, regular breaks, heat and gentle movement. None of it is dramatic, and together it does more than anything else in the first few weeks.
Choosing a cushion
Look for a cushion with a cut-out or a U-shaped gap at the back, so your tailbone is suspended over a gap and your weight rests on the sitting bones instead. A firm wedge shape suits most people, since it also tips the pelvis slightly forward and off the coccyx.
Firm foam usually beats very soft padding, which lets you sink until the tailbone finds the seat anyway. Inflatable ring cushions help some people, but they can roll the pelvis backwards and increase pressure on the coccyx, so they are worth trying rather than assuming. Keep the cushion in the place you sit most, which for many people is the car rather than the office.
How you sit
Aim to sit upright or very slightly forward, with your weight on your sitting bones, feet flat and hips level with or just above your knees. The position to avoid is slumping backwards into a soft chair, which rolls the pelvis under and puts your weight straight onto the tailbone. Deep sofas, low bucket seats and backwards-tilted stools are the usual offenders at home, and a firmer dining chair with a wedge cushion is often more comfortable than the sofa.
Breaking up the sitting
Stand up every twenty to thirty minutes, even briefly. The coccyx tolerates short periods of loading far better than long unbroken ones, and a two-minute stand resets the clock. On a long drive, plan stops; on a flight, take an aisle seat.
TIP
Set a quiet timer for the first fortnight. Most people with coccyx pain do not sit badly so much as sit continuously, and standing briefly every half hour usually helps more than any single purchase.
Heat and gentle movement
Heat before a long sitting session relaxes the pelvic floor and buttock muscles that attach to the coccyx, and many people find it more useful than ice after the first few days. Gentle hip and lower back mobility, easy walking, and relaxed breathing that lets the pelvic floor soften all help. Avoid forcing deep stretches, and avoid sitting through the pain to test it. Your non-surgical care options start here for a reason: this is the stage where most people get better.
How long does coccyx pain take to settle?
Honestly, longer than most people expect. Many improve substantially over several weeks, and the majority settle within a few months. Recovery after a fall or after childbirth can take longer, and a bruised or fractured coccyx often remains tender for some weeks after the bone itself has healed.
It also does not improve in a straight line. A good week followed by a long car journey and a bad weekend is the normal shape of this condition, not a sign that you have undone your progress. Judge it by the trend across weeks: how long you can sit before it bites, and how sharp standing up feels.
NOTE
A useful way to track progress is sitting tolerance rather than pain score. If you could manage ten minutes in a chair a month ago and can now manage thirty, you are improving even if the peak pain still feels similar.
A smaller group has pain that persists beyond a few months. That is well recognized, and it is the point at which more targeted treatment is worth considering.
What happens at an assessment
An assessment for coccyx pain is mostly conversation and careful examination, with imaging used selectively rather than routinely.
Expect questions about how it started, exactly where it hurts, what sitting does to it, and whether bowel movements, sex or standing up change it. Examination involves gently pressing along the coccyx to locate the tender segment, checking the surrounding muscles and hips, and assessing how you sit and rise. With your consent, an internal examination is sometimes offered, because it is the most reliable way to assess coccyx movement and pelvic floor tension. It is always optional, and it should be explained fully first.
Imaging is not always necessary. An X-ray can show a fracture or an unusually angled coccyx, and some centers use films taken sitting and standing to see how the bone moves. An MRI is reserved for persistent pain or where something in the history raises a concern, since it shows soft tissue, inflammation and the rare causes listed below.
Treatment when self-care is not enough
If several weeks of cushioning, posture changes and activity adjustment have not moved things along, the next steps are physiotherapy and, for stubborn cases, a targeted injection. Surgery sits a long way down the list.
Physiotherapy, including pelvic floor work
Physiotherapy for coccydynia looks different from general back rehabilitation. Because the pelvic floor muscles attach to the coccyx, a tense or overactive pelvic floor can keep pulling on an already irritated joint. A physiotherapist trained in this area can work on releasing that tension, mobilizing the coccyx itself, and correcting the sitting and standing habits that keep provoking it. Specialist spine physiotherapy is the mainstay of treatment for persistent tailbone pain.
Injections
An injection of local anesthetic, often with a steroid, placed around the coccyx or the small nerve bundle in front of it can substantially reduce pain in people whose symptoms have not settled. It is usually done with imaging guidance for accuracy. The honest framing is that it is not a cure in itself: its value is calming the area enough that you can sit, move and complete a rehabilitation program.
Surgery is genuinely rare
Removal of the coccyx, a coccygectomy, exists for the small number of people with severe, long-standing pain that has not responded to thorough non-surgical care, ideally with a clear structural explanation such as demonstrated instability. It is not a routine operation, recovery is slow, and selection matters enormously. The vast majority of people with tailbone pain will never need to consider it.
The uncommon causes worth excluding
A small number of cases are caused by something other than mechanical irritation: fracture, infection, or, rarely, a tumor in or near the sacrum and coccyx. These are uncommon, but they are the reason persistent or unusual tailbone pain deserves proper assessment rather than indefinite self-management.
Infection in this region includes a pilonidal sinus or abscess, which typically produces redness, swelling, warmth or discharge just above the crease of the buttocks. Bone infection is rarer and tends to come with feeling generally unwell. Tumors in this area are rare, and the pattern that raises suspicion is pain that is constant, present at night and unrelated to sitting, sometimes with weight loss.
WARNING
Seek medical assessment promptly if tailbone pain comes with fever or feeling unwell, pain that wakes you at night or is unrelated to sitting, unexplained weight loss, a lump, swelling, redness or discharge near the tailbone, or any loss of bladder or bowel control, numbness around the groin, or new leg weakness. These are uncommon, but they need to be checked rather than waited out.
Nerve symptoms deserve particular attention, since they point away from the coccyx and towards the nerves above it. If you have numbness or weakness spreading into the legs, read our guidance on leg numbness and weakness warning signs.
When to be assessed
Book an assessment if tailbone pain is still limiting what you can do after around six to eight weeks of sensible self-care, if it followed a significant fall, if it began after childbirth and is not easing, or if any of the warning signs above are present.
There is no prize for waiting. Coming in earlier does not mean heading towards surgery, it usually means the right cushion advice, the right physiotherapy referral, and confirmation that nothing else is going on.
The calm summary
Tailbone pain is a nuisance out of all proportion to the size of the bone, and it can take a while, but the overall picture is a good one. Most coccydynia settles with patience and the right adjustments. Most of the rest responds to focused physiotherapy, with an injection where it is needed. Only a very small number of people ever need anything more.
If you are in the thick of it now, the useful things are ordinary: a cushion that suits you, a chair that does not tip you backwards, and standing up more often than feels necessary. Give it time, judge progress across weeks rather than days, and get it looked at if it stops moving in the right direction.
Common questions
Why does my tailbone hurt when I sit?
Sitting loads the coccyx directly, and leaning back loads it more. If the small joints at the base of the spine or the surrounding ligaments and pelvic floor attachments are irritated, every minute in a chair keeps provoking them. That is why coccyx pain is usually worst on hard seats and eases when you stand or walk.
How long does tailbone pain last?
Many people improve over several weeks, and most settle within a few months. Recovery after a fall or childbirth can take longer, and it rarely runs in a straight line. Good and bad days are normal. Pain that is still limiting you after around eight weeks of sensible self-care is worth having assessed.
What is the best cushion for coccyx pain?
A wedge cushion with a cut-out or U-shaped gap at the back usually works best, because it suspends the tailbone so your weight rests on the sitting bones instead. Firm foam tends to help more than very soft padding. Inflatable ring cushions suit some people but can tip the pelvis backwards and increase pain.
Can you break your tailbone?
Yes. A fall onto the bottom can fracture or dislocate the coccyx, and bruising of the bone is even more common. Both cause intense pain on sitting and on rising. Treatment is much the same either way, since a coccyx fracture is managed with cushioning, activity changes and time rather than with a cast or an operation.
Is tailbone pain a sign of something serious?
Rarely. The large majority of coccyx pain is mechanical and settles. Warning signs that need prompt assessment include fever, pain that wakes you at night, unexplained weight loss, a lump, swelling or discharge near the tailbone, and any change in bladder or bowel control or numbness around the groin.
What helps tailbone pain at home?
Use a coccyx cushion, sit slightly forward on your sitting bones rather than slumped back, and stand up every twenty to thirty minutes. Heat before sitting for long periods helps many people, alongside gentle hip and lower back mobility. Avoid long drives, hard benches and deep sofas while the area is settling.
