Coccyx pain (coccydynia)

Coccyx pain (coccydynia): causes, what really helps, and when to seek help

Article written and reviewed by a pharmacist graduated from the Faculty of Paris.

Good to know: Coccyx pain, also called coccydynia, is often underestimated but can be very disabling, especially when sitting for long periods.

The coccyx is a small bone at the end of the spine. When irritated or injured, it may cause localized pain, often sharp, that worsens when sitting, standing up from a chair, or leaning backward.

1) Common causes of coccyx pain

Fall or direct trauma
Prolonged sitting on hard surfaces
Repeated micro-trauma (cycling, driving)
Childbirth
Weight changes
More rarely: inflammation or bone disorders

2) Typical symptoms

Localized pain at the bottom of the spine
Discomfort when sitting
Pain when standing up
Relief when standing or lying down

3) What really helps (without making it worse)

✅ Adjust sitting position

Avoid hard chairs. A slight forward tilt can reduce pressure on the coccyx.

✅ Use a coccyx cushion

Cushions with a rear cut-out significantly reduce direct pressure and improve comfort.

✅ Ice or heat

Ice may help after trauma or during inflammation. Gentle heat can relax surrounding muscles.

✅ Relative rest

Limit aggravating activities while keeping light daily movement.
