Tailbone Pain (Coccydynia): Causes, Home Treatment, and When to See a Doctor

Tailbone pain, medically called coccydynia, is pain centered at the very bottom of the spine that typically worsens with sitting, especially on hard surfaces, or when transitioning from sitting to standing.

How Tailbone Pain Feels

Coccydynia typically causes pain in the midline just below the sacrum and above the anus. It is usually worst when sitting — especially leaning back on a hard surface — and when standing up from a seat; many people feel better when standing or walking. Pain that shoots down the leg, or sits mainly in the lower back or buttock, points toward a different problem (see sciatica or lower back pain causes).

Common Causes

A fall directly onto the tailbone, childbirth, prolonged sitting on a hard or narrow surface, and repetitive strain (such as from cycling) are the most common triggers. Less commonly, it can result from a local infection, a bone spur, or, rarely, a tumor.

Who Is More Likely to Get It

Tailbone pain is more common in women, partly due to a wider, more exposed pelvic anatomy, and in people who are overweight or significantly underweight, both of which affect how weight is distributed while sitting.

Treatment

Most cases improve within a few weeks to months with simple measures: using a cushioned, coccyx-shaped seat cushion, avoiding prolonged sitting, applying ice or heat, and taking over-the-counter pain relievers. Gentle stretching and, for persistent cases, physical therapy targeting the pelvic floor can also help.

What Helps at Home

• Take pressure off the tailbone: a wedge- or U-shaped coccyx cushion, and leaning slightly forward while sitting so your weight rests on the sit bones rather than the coccyx.
• Break up sitting: stand or shift position regularly, and avoid hard or narrow seats and long car journeys where you can.
• Heat or cold applied to the area for short periods.
• Over-the-counter pain relief: anti-inflammatory painkillers are a common first-line option; ask a pharmacist or doctor first if you have stomach, kidney or heart conditions, are pregnant, or take blood thinners.
• Pelvic-floor relaxation exercises: if the muscles around the coccyx are tight, a physiotherapist can teach relaxation and stretching techniques.

If Pain Lasts: What a Doctor Can Offer

Doctors usually start with an examination, and may request an X-ray or MRI — for example after a fall, or when the cause is unclear. When pain persists despite the steps above, options described in the medical literature include targeted physical therapy, local anesthetic or corticosteroid injections, and nerve blocks from a pain-management specialist. Surgery to remove the coccyx (coccygectomy) is reserved for rare, persistent cases that have not responded to other treatment. An orthopedic doctor can advise which route suits you.

Tailbone Pain After Pregnancy or Childbirth

Childbirth is one of the recognized triggers. Most people are managed with the same conservative steps (cushion, posture, physiotherapy); mention the pain to your obstetrician or doctor rather than assuming it is just part of recovery if it is severe or not improving.

Could It Be Something Else?

A painful, swollen or red lump at the top of the buttock crease, especially with pus or fever, can be an infection near the tailbone (pilonidal disease) and needs a doctor rather than a cushion. Pain when passing stool may relate to the rectum or hemorrhoids. Pain that shoots down a leg is more typical of the sciatic nerve — see back pain.

When to See a Doctor

See a doctor if pain follows a significant fall or injury, is severe, doesn't improve after several weeks of self-care, or comes with numbness or bowel/bladder changes.
