Understanding the condition
What is Coccydynia?
Coccydynia is pain localised to the coccyx, the small triangular bone at the very base of the spine. The coccyx serves as an important attachment point for the muscles, tendons, and ligaments of the pelvic floor, which is why pain there so often disrupts sitting, movement, bowel function, and sexual activity. When the coccyx becomes inflamed, injured, or destabilised, the surrounding soft tissue reacts and the pain can become persistent and deeply limiting.
Acute coccydynia often resolves on its own within a few weeks. But when pain persists beyond that, it is a sign that the underlying driver has not been addressed. Chronic coccydynia responds well to targeted physical treatment. Waiting it out indefinitely is not a strategy.
The most common causes are a direct fall onto the coccyx, repetitive strain from cycling or rowing, childbirth, and prolonged sitting on hard surfaces. In around one third of cases no clear cause can be identified. Regardless of the origin, the mechanisms of pain are well understood and can be addressed with the right treatment.
