What Is Coccydynia?
Coccydynia is pain in or around the coccyx (tailbone)—the small triangular bone at the bottom of your spine. It makes sitting painful, sometimes unbearably so.
The coccyx is small but important. It's an attachment point for muscles and ligaments of the pelvic floor, and it bears weight when you sit.
What Causes Tailbone Pain?
Trauma
Direct injury:
Falling onto tailbone (most common cause)Childbirth (pressure or fracture)Repeated minor trauma (cycling, rowing)Non-Traumatic Causes
Hypermobility:
Coccyx moves too muchMore common in womenHypomobility:
Coccyx is too stiffCan occur after injury healingMuscle tension:
Pelvic floor dysfunctionCoccyx muscle spasmOther Factors
Prolonged sitting on hard surfacesPoor sitting postureObesity (changes sitting mechanics)Rapid weight loss (less cushioning)Rare: tumors, infectionSymptoms
Classic Presentation
Pain directly at tailboneWorse when sitting (especially on hard surfaces)Pain when going from sitting to standingPain during bowel movementsPain with sex (some cases)Relief when standing or lying downDuration
Acute: following injury, often resolves in weeks to monthsChronic: persists more than 2 monthsDiagnosis
Physical Exam
Tenderness over coccyxInternal exam may be needed to assess mobility and pelvic floorImaging
X-rays:
Standing and sitting viewsCan show abnormal movementMRI:
If fracture, tumor, or other pathology suspectedTreatment
Cushioning (First Line)
Coccyx cushion (donut pillow):
Cutout at back to reduce pressure on tailboneUse on all sitting surfacesEssential for recoveryProper sitting:
Lean slightly forwardWeight on thighs, not tailboneAvoid prolonged sittingPain Management
Ice:
15-20 minutes after aggravating activitiesCan help with acute inflammationHeat:
May help with muscle relaxationTry both, use what worksNSAIDs:
Over-the-counter anti-inflammatoriesHelp with pain and swellingPelvic Floor Treatment
Why it matters:
Many cases involve pelvic floor muscle tension or spasm. Treating this is often key.
Pelvic floor physical therapy:
Internal and external techniquesMuscle releaseCoordination trainingOften very effectiveManual Therapy
Internal coccyx manipulation:
Done by specialist (pelvic PT or physician)Mobilizes restricted coccyxCan provide significant reliefExercises
Pelvic floor relaxation:
Diaphragmatic breathingReverse Kegels (gentle bearing down)Focus on releasing, not tighteningHip stretches:
Piriformis stretchHip flexor stretchMay reduce tension on coccyx attachmentsGentle core work:
Avoid sit-ups or crunchesStability work in pain-free positionsInjections
Corticosteroid Injection
When used:
Failed 4-8 weeks conservative treatmentSignificant painHow it works:
Injection around coccyxReduces inflammationOften provides reliefGanglion Impar Block
Blocks the nerve bundle near coccyxFor refractory casesSurgery (Coccygectomy)
Rarely Needed
Last resort after all conservative measures fail.
Indications
Severe, disabling painFailed 6+ months conservative treatmentFailed injectionsThe Procedure
Removal of part or all of coccyxOutpatient surgeryVariable outcomes (60-90% improvement)Recovery
4-6 weeks before sitting normallyFull recovery several monthsWound near anus requires careful hygieneSitting Modifications

Consider for work—reduces sitting time significantly.
Timeline for Recovery
Acute Cases
Most improve within weeks to monthsCushioning + time often enoughChronic Cases

Tailbone pain is genuinely miserable—sitting is unavoidable in daily life. The good news is that most cases respond to cushioning, time, and pelvic floor treatment if needed. Get a good coccyx cushion, sit properly, and give it time. If it persists, pelvic floor physical therapy is often the key.
