Idiopathic Coccydynia: What to Know

Coccydynia describes pain around the coccyx, the small bone at the base of the spine. It may be worse when sitting, leaning back, standing from a chair, or having a bowel movement. Idiopathic means that an examination and available history have not identified a definite trigger such as a fall, childbirth-related strain, prolonged pressure, or another condition. It does not mean the pain is imaginary; sensitive joints, muscles, ligaments, and nerves around the coccyx can all contribute.

A clinician considers the pain pattern, skin and neurological findings, bowel or bladder symptoms, and any history of injury. Further tests are guided by the examination rather than automatically needed for every person.

Use a cushion that reduces direct pressure on the tailbone, change position often, and take short standing or walking breaks from sitting. Keep bowel movements comfortable with fluids, fibre, and advice suited to your health. Gentle hip and pelvic movement may help, but stop exercises that sharply increase pain. A physiotherapist can assess sitting posture, pelvic floor and nearby muscle tension, then build a gradual programme; see [Physiotherapy](/treatments/physiotherapy-and-rehabilitation/physiotherapy/).

Pain relief options should match your medical history. If symptoms continue, a clinician may discuss targeted treatment such as a [Cortisone Injection](/treatments/non-surgical-orthopedics/cortisone-injection/) after explaining expected benefits and possible risks.

Seek prompt assessment for new weakness, numbness around the groin, loss of bladder or bowel control, fever, unexplained weight change, or pain after a major injury. Arrange review if pain is worsening, prevents sleep or ordinary sitting, or continues despite practical changes. A painful lump, drainage, or skin redness near the cleft also needs examination because it may point to a problem other than coccydynia.

Ask what findings support coccydynia, whether another cause needs checking, which cushion and movements suit you, and when physiotherapy or an injection should be considered.
