Coccygodynia, also known as sacrum or coccyx pain, is quite a rare and little-known condition that causes pain in the lowest part of the spine and the coccyx.

The pain is usually worse when sitting, getting to your feet, when pressure in the area increases and with constipation. It is usually caused by serious or undetected injuries, after childbirth, in rare cases by infections or tumours that cause irritation, dislocation or inflammation of the joint between the sacrum and coccyx, or the joints between the four coccygeal vertebrae.

Conservative treatment of coccygodynia consists of anti-inflammatory drugs, postural hygiene measures to prevent pressure being put on the area (using a bespoke pillow, preventing constipation with a fibre-rich diet and water) and spinal manipulation.

If conservative treatment fails, the Barcelona Spine Institute can block the sacrococcygeal joint and the ganglion impar, a group of nerve cells responsible for the sensitivity of the area that is located in front of the joint, and which is reached by passing a needle through the joint. A mixture of anaesthetics and corticosteroids is used, which provides an analgesic effect lasting for months or years.
